Executive Order - Energy and Power Perspective
The tariffs imposed by the Executive Order (EO) are expected to significantly impact the energy and infrastructure sectors. New build energy projects in the United States heavily depend on importing components such as inverters, transformers, cabling, solar panels, mounting racks, and batteries from regions such as Southeast Asia, China, and the European Union. These tariffs are likely to affect all energy and infrastructure projects. We are seeing large capital projects across the United States impose caveats within their EPC contracts; allowing for steep and continual price adjustments upward. This is impacting billions of dollars of critical material and contractual obligated componentry. This also includes all materials with high volatility (steel, copper, aluminum). Not only are projects costs on the rise but so are supply chain disruptions, potentially causing delays in project timelines and/or project cancellations. The United States continues to grow in energy demand requirements, provided the vast deployment of data centers. Because of this grid reliability, modernization and new build implementation is critical in the coming decade. The tariffs are likely to have a large impact on these projects as well, given their requirement for componentry from all the regions impacted. As this situation continues to develop, the full implications and responses for the energy and infrastructure industry will become more apparent.

Virtual reality training tool helps nurses learn patient-centered care
University of Delaware computer science students have developed a digital interface as a two-way system that can help nurse trainees build their communication skills and learn to provide patient-centered care across a variety of situations. This virtual reality training tool would enable users to rehearse their bedside manner with expectant mothers before ever encountering a pregnant patient in person. The digital platform was created by students in Assistant Professor Leila Barmaki’s Human-Computer Interaction Laboratory, including senior Rana Tuncer, a computer science major, and sophomore Gael Lucero-Palacios. Lucero-Palacios said the training helps aspiring nurses practice more difficult and sensitive conversations they might have with patients. "Our tool is targeted to midwifery patients,” Lucero-Palacios said. “Learners can practice these conversations in a safe environment. It’s multilingual, too. We currently offer English or Turkish, and we’re working on a Spanish demo.” This type of judgement-free rehearsal environment has the potential to remove language barriers to care, with the ability to change the language capabilities of an avatar. For instance, the idea is that on one interface the “practitioner” could speak in one language, but it would be heard on the other interface in the patient’s native language. The patient avatar also can be customized to resemble different health stages and populations to provide learners a varied experience. Last December, Tuncer took the project on the road, piloting the virtual reality training program for faculty members in the Department of Midwifery at Ankara University in Ankara, Turkey. With technical support provided by Lucero-Palacios back in the United States, she was able to run a demo with the Ankara team, showcasing the UD-developed system’s interactive rehearsal environment’s capabilities. Last winter, University of Delaware senior Rana Tuncer (left), a computer science major, piloted the virtual reality training program for Neslihan Yilmaz Sezer (right), associate professor in the Department of Midwifery, Ankara University in Ankara, Turkey. Meanwhile, for Tuncer, Lucero-Palacios and the other students involved in the Human-Computer Interaction Laboratory, developing the VR training tool offered the opportunity to enhance their computer science, data science and artificial intelligence skills outside the classroom. “There were lots of interesting hurdles to overcome, like figuring out a lip-sync tool to match the words to the avatar’s mouth movements and figuring out server connections and how to get the languages to switch and translate properly,” Tuncer said. Lucero-Palacios was fascinated with developing text-to-speech capabilities and the ability to use technology to impact patient care. “If a nurse is well-equipped to answer difficult questions, then that helps the patient,” said Lucero-Palacios. The project is an ongoing research effort in the Barmaki lab that has involved many students. Significant developments occurred during the summer of 2024 when undergraduate researchers Tuncer and Lucero-Palacios contributed to the project through funding support from the National Science Foundation (NSF). However, work began before and continued well beyond that summer, involving many students over time. UD senior Gavin Caulfield provided foundational support to developing the program’s virtual environment and contributed to development of the text-to-speech/speech-to-text capabilities. CIS doctoral students Fahim Abrar and Behdokht Kiafar, along with Pinar Kullu, a postdoctoral fellow in the lab, used multimodal data collection and analytics to quantify the participant experience. “Interestingly, we found that participants showed more positive emotions in response to patient vulnerabilities and concerns,” said Kiafar. The work builds on previous research Barmaki, an assistant professor of computer and information sciences and resident faculty member in the Data Science Institute, completed with colleagues at New Jersey Institute of Technology and University of Central Florida in an NSF-funded project focused on empathy training for healthcare professionals using a virtual elderly patient. In the project, Barmaki employed machine learning tools to analyze a nursing trainee’s body language, gaze, verbal and nonverbal interactions to capture micro-expressions (facial expressions), and the presence or absence of empathy. “There is a huge gap in communication when it comes to caregivers working in geriatric care and maternal fetal medicine,” said Barmaki. “Both disciplines have high turnover and challenges with lack of caregiver attention to delicate situations.” UD senior Rana Tuncer (center) met with faculty members Neslihan Yilmaz Sezer (left) and Menekse Nazli Aker (right) of Ankara University in Ankara, Turkey, to educate them about the virtual reality training tool she and her student colleagues have developed to enhance patient-centered care skills for health care professionals. When these human-human interactions go wrong, for whatever reason, it can extend beyond a single patient visit. For instance, a pregnant woman who has a negative health care experience might decide not to continue routine pregnancy care. Beyond the project’s potential to improve health care professional field readiness, Barmaki was keen to note the benefits of real-world workforce development for her students. “Perceptions still exist that computer scientists work in isolation with their computers and rarely interact, but this is not true,” Barmaki said, pointing to the multi-faceted team members involved in this project. “Teamwork is very important. We have a nice culture in our lab where people feel comfortable asking their peers or more established students for help.” Barmaki also pointed to the potential application of these types of training environments, enabled by virtual reality, artificial intelligence and natural language processing, beyond health care. With the framework in place, she said, the idea could be adapted for other types of training involving human-human interaction, say in education, cybersecurity, even in emerging technology such as artificial intelligence (AI). Keeping people at the center of any design or application of this work is critical, particularly as uses for AI continue to expand. “As data scientists, we see things as spreadsheets and numbers in our work, but it’s important to remember that the data is coming from humans,” Barmaki said. While this project leverages computer vision and AI as a teaching tool for nursing assistants, Barmaki explained this type of system can also be used to train AI and to enable more responsible technologies down the road. She gave the example of using AI to study empathic interactions between humans and to recognize empathy. “This is the most important area where I’m trying to close the loop, in terms of responsible AI or more empathy-enabled AI,” Barmaki said. “There is a whole area of research exploring ways to make AI more natural, but we can’t work in a vacuum; we must consider the human interactions to design a good AI system.” Asked whether she has concerns about the future of artificial intelligence, Barmaki was positive. “I believe AI holds great promise for the future, and, right now, its benefits outweigh the risks,” she said.
NASA Grant Funds Research Exploring Methods of Training Vision-Based Autonomous Systems
Conducting research at 5:30 a.m. may not be everybody’s first choice. But for Siddhartha Bhattacharyya and Ph.D. students Mohammed Abdul, Hafeez Khan and Parth Ganeriwala, it’s an essential part of the process for their latest endeavor. Bhattacharyya and his students are developing a more efficient framework for creating and evaluating image-based machine learning classification models for autonomous systems, such as those guiding cars and aircraft. That process involves creating new datasets with taxiway and runway images for vision-based autonomous aircraft. Just as humans need textbooks to fuel their learning, some machines are taught using thousands of photographs and images of the environment where their autonomous pupil will eventually operate. To help ensure their trained models can identify the correct course to take in a hyper-specific environment – with indicators such as centerline markings and side stripes on a runway at dawn – Bhattacharyya and his Ph.D. students chose a December morning to rise with the sun, board one of Florida Tech’s Piper Archer aircraft and photograph the views from above. Bhattacharyya, an associate professor of computer science and software engineering, is exploring the boundaries of operation of efficient and effective machine-learning approaches for vision-based classification in autonomous systems. In this case, these machine learning systems are trained on video or image data collected from environments including runways, taxiways or roadways. With this kind of model, it can take more than 100,000 images to help the algorithm learn and adapt to an environment. Today’s technology demands a pronounced human effort to manually label and classify each image. This can be an overwhelming process. To combat that, Bhattacharyya was awarded funding from NASA Langley Research Center to advance existing machine learning/computer vision-based systems, such as his lab’s “Advanced Line Identification and Notation Algorithm” (ALINA), by exploring automated labeling that would enable the model to learn and classify data itself – with humans intervening only as necessary. This measure would ease the overwhelming human demand, he said. ALINA is an annotation framework that Hafeez and Parth developed under Bhattacharyya’s guidance to detect and label data for algorithms, such as taxiway line markings for autonomous aircraft. Bhattacharyya will use NASA’s funding to explore transfer learning-based approaches, led by Parth, and few-shot learning (FSL) approaches, led by Hafeez. The researchers are collecting images via GoPro of runways and taxiways at airports in Melbourne and Grant-Valkaria with help from Florida Tech’s College of Aeronautics. Bhattacharyya’s students will take the data they collect from the airports and train their models to, in theory, drive an aircraft autonomously. They are working to collect diverse images of the runways – those of different angles and weather and lighting conditions – so that the model learns to identify patterns that determine the most accurate course regardless of environment or conditions. That includes the daybreak images captured on that December flight. “We went at sunrise, where there is glare on the camera. Now we need to see if it’s able to identify the lines at night because that’s when there are lights embedded on the taxiways,” Bhattacharyya said. “We want to collect diverse datasets and see what methods work, what methods fail and what else do we need to do to build that reliable software.” Transfer learning is a machine learning technique in which a model trained to do one task can generalize information and reuse it to complete another task. For example, a model trained to drive autonomous cars could transfer its intelligence to drive autonomous aircraft. This transfer helps explore generalization of knowledge. It also improves efficiency by eliminating the need for new models that complete different but related tasks. For example, a car trained to operate autonomously in California could retain generalized knowledge when learning how to drive in Florida, despite different landscapes. “This model already knows lines and lanes, and we are going to train it on certain other types of lines hoping it generalizes and keeps the previous knowledge,” Bhattacharyya explained. “That model could do both tasks, as humans do.” FSL is a technique that teaches a model to generalize information with just a few data samples instead of the massive datasets used in transfer learning. With this type of training, a model should be able to identify an environment based on just four or five images. “That would help us reduce the time and cost of data collection as well as time spent labeling the data that we typically go through for several thousands of datasets,” Bhattacharyya said. Learning when results may or may not be reliable is a key part of this research. Bhattacharyya said identifying degradation in the autonomous system’s performance will help guide the development of online monitors that can catch errors and alert human operators to take corrective action. Ultimately, he hopes that this research can help create a future where we utilize the benefits of machine learning without fear of it failing before notifying the operator, driver or user. “That’s the end goal,” Bhattacharyya said. “It motivates me to learn how the context relates to assumptions associated with these images, that helps in understanding when the autonomous system is not confident in its decision, thus sending an alert to the user. This could apply to a future generation of autonomous systems where we don’t need to fear the unknown – when the system could fail.” Siddhartha (Sid) Bhattacharyya’s primary area of research expertise/interest is in model based engineering, formal methods, machine learning engineering, and explainable AI applied to intelligent autonomous systems, cyber security, human factors, healthcare, explainable AI, and avionics. His research lab ASSIST (Assured Safety, Security, and Intent with Systematic Tactics) focuses on the research in the design of innovative formal methods to assure performance of intelligent systems, machine learning engineering to characterize intelligent systems for safety and model based engineering to analyze system behavior. Siddhartha Bhattacharyya is available to speak with media. Contact Adam Lowenstein, Director of Media Communications at Florida Institute of Technology at adam@fit.edu to arrange an interview today.
Aston University study reveals the illusion of ‘dazzle’ paint on World War I battleships
The Zealandia in wartime dazzle paint. Image: Australian National Maritime Museum on The Commons Geometric ‘dazzle’ camouflage was used on ships in WWI to confuse enemy onlookers as to the direction and speed of the ship Timothy Meese and Samantha Strong reanalysed historic data from 1919 and found that the ‘horizon effect’ is more effective for confusion When viewing a ship at distance, it often appears to be travelling along the horizon, regardless of its actual direction of travel – this is the ‘horizon effect’. A new analysis of 105-year-old data on the effectiveness of ‘dazzle’ camouflage on battleships in World War I by Aston University researchers Professor Tim Meese and Dr Samantha Strong has found that while dazzle had some effect, the ‘horizon effect’ had far more influence when it came to confusing the enemy. During World War I, navies experimented with painting ships with ‘dazzle’ camouflage – geometric shapes and stripes – in an attempt to confuse U-boat captains as to the speed and direction of travel of the ships and make them harder to attack. The separate ‘horizon effect’ is when a person looks at a ship in the distance, and it appears to be travelling along the horizon, regardless of its actual direction of travel. Ships travelling at an angle of up to 25° relative to the horizon appear to be travelling directly along it. Even with those at a greater angle to the horizon, onlookers significantly underestimate the angle. Despite widespread use of dazzle camouflage, it was not until 1919 that a proper, quantitative study was carried out, by MIT naval architecture and marine engineering student Leo Blodgett for his degree thesis. He painted model ships in dazzle patterns and placed them in a mechanical test theatre with a periscope, like those used by U-boat captains, to measure how much onlookers’ estimations of the ships’ direction of travel deviated from their actual direction of travel. Professor Meese and Dr Strong realised that while the data collected by Blodgett was useful, his methods of experimental design fell short of modern standards. He’d found that dazzle camouflage worked, but the Aston University team suspected that dazzle alone was not responsible for the results seen, cleaned the data and designed new analysis to better understand what it really shows. Dr Strong, a senior lecturer at Aston University’s School of Optometry, said: “It's necessary to have a control condition to draw firm conclusions, and Blodgett's report of his own control was too vague to be useful. We ran our own version of the experiment using photographs from his thesis and compared the results across the original dazzle camouflage versions and versions with the camouflage edited out. Our experiment worked well. Both types of ships produced the horizon effect, but the dazzle imposed an additional twist.” If the errors made by the onlookers in the perceived direction of travel of the ship were entirely due to the ‘twist’ on perspective caused by dazzle paintwork, the bow, or front, of the ship, would always be seen to twist away from its true direction. However, Professor Meese and Dr Strong instead showed that when the true direction was pointing away from the observer, the bow was often perceived to twist towards the observer instead. Their detailed analysis showed a small effect of twist from the dazzle camouflage but a much larger one from the horizon effect. Sometimes these effects were in competition, sometimes in harmony. Professor Meese, a professor of vision science at the School of Optometry, said: “We knew already about the twist and horizon effects from contemporary computer-based work with colleagues at Abertay University. The remarkable finding here is that these same two effects, in similar proportions, are clearly evident in participants familiar with the art of camouflage deception, including a lieutenant in a European navy. This adds considerable credibility to our earlier conclusions by showing that the horizon effect – which has nothing to do with dazzle – was not overcome by those best placed to know better. “This is a clear case where visual perception is more powerful than knowledge. In fact, back in the dazzle days, the horizon effect was not identified at all, and Blodgett's measurements of perceptual bias were attributed entirely to the camouflage, deceiving the deceivers.” Professor Meese and Dr Strong say that more work is required to fully understand how dazzle might have increased perceptual uncertainty of direction and speed but also the geometry behind torpedo-aiming tactics that might have supported some countermeasures.

Transforming Work Meetings: Strategies for More Effective and Engaging Collaboration
I’m sure you’ve heard it before—maybe from colleagues, leaders, friends or even yourself: “I am dreading my upcoming meeting.” Work meetings often have a bad reputation. People commonly complain about their frequency, the lack of purpose or how tedious they can feel. Memes and phrases like “this meeting should have been an email” have become cultural staples. Yet, over 55 million meetings take place daily in the United States. The average employee spends nearly 10 hours each week in meetings, and for executives, this number jumps to nearly half their working time. If meetings are as unproductive as people claim, consider how much of a CEO’s salary is wasted on ineffective discussions! Rather than seeing this as a hopeless situation, I view it as an opportunity. My research focuses on making work meetings more effective, engaging and satisfying, ultimately leading to better outcomes for individuals, teams and organizations. I call myself a “meeting scientist,” studying and sharing best practices for every stage of a meeting—before, during and after. BEFORE THE MEETING Meeting success starts with preparation. Research suggests having a clear and purposeful agenda shared in advance is a crucial factor in making meetings more effective. Be intentional about your attendee list—over-inviting can reduce inclusion and participation. Focus on who absolutely needs to be there, and consider listing others as optional participants. Aim to keep meetings as short as possible while still achieving your objectives. Avoid defaulting to the hourlong meeting just because it’s standard practice. Designing a meeting requires intention—every element should have a purpose. “My research focuses on making work meetings more effective, engaging and satisfying, ultimately leading to better outcomes for individuals, teams and organizations.” DURING THE MEETING Whether you’re facilitating or participating, engagement is key. Actively involve attendees, ask and answer questions and ensure quieter voices are included. Consider using round-robin discussions to ensure everyone has a chance to speak, incorporating interactive elements, like polls or brainstorming sessions, and creating a safe environment where participants feel comfortable sharing their thoughts. AFTER THE MEETING The meeting isn’t over until next steps are clearly defined. Take five minutes to recap key points, decisions and action items. Assign responsibilities and deadlines to specific individuals—Joe should leave knowing his next task, and Kate should understand when her deliverables are due. All participants should walk away feeling that something was accomplished, they have a clear path forward and their time was well spent. While these best practices might seem obvious, they’re surprisingly rare—75% of managers report never being trained on how to design or lead a meeting, even though they spend a significant portion of their roles in meetings. This lack of training is a missed opportunity to foster more productive and engaging collaboration. Looking to know more? We can help. Dr. Liana M.

3D-printed lung model helps researchers study aerosol deposition in the lungs
Treating respiratory diseases is challenging. Inhalable medicines depend on delivering particles to the right lung areas, which is complicated by factors like the drug, delivery method and patient variability, or even exposure to smoke or asbestos particles. University of Delaware researchers have developed an adaptable 3D lung model to address this issue by replicating realistic breathing maneuvers and offering personalized evaluation of aerosol therapeutics. “If it's something environmental and toxic that we're worried about, knowing how far and how deep in the lung it goes is important,” said Catherine Fromen, University of Delaware Centennial Associate Professor for Excellence in Research and Education in the Department of Chemical and Biomolecular Engineering. “If it's designing a better pharmaceutical drug for asthma or a respiratory disease, knowing exactly where the inhaled aerosol lands and how deep the medicine can penetrate will predict how well that works.”that can replicate realistic breathing maneuvers and offer personalized evaluation of aerosol therapeutics under various breathing conditions. Fromen and two UD alumni have submitted a patent application on the 3D lung model invention through UD’s Office of Economic Innovation and Partnerships (OEIP), the unit responsible for managing intellectual property at UD. In a paper published in the journal Device, Fromen and her team demonstrate how their new 3D lung model can advance understanding of how inhalable medications behave in the upper airways and deeper areas of the lung. This can provide a broader picture on how to predict the effectiveness of inhalable medications in models and computer simulations for different people or age groups. The researchers detail in the paper how they built the 3D structure and what they’ve learned so far. Valuable research tool The purpose of the lung is gas exchange. In practice, the lung is often approximated as the size of a tennis court that is exchanging oxygen and carbon dioxide with the bloodstream in our bodies. This is a huge surface area, and that function is critical — if your lungs go down, you're in trouble. Fromen described this branching lung architecture like a tree that starts with a trunk and branches out into smaller and smaller limbs, ranging in size from a few centimeters in the trachea to about 100 microns (roughly the combined width of two hairs on your head) in the lung’s farthest regions. These branches create a complex network that filters aerosols as they travel through the lung. Just as tree branches end in leaves, the lung’s branches culminate in delicate, leaf-like structures called alveoli, where gases are exchanged. “Those alveoli in the deeper airways make the surface area that provides this necessary gas exchange, so you don't want environmental things getting in there where they can damage these sensitive, finer structures,” said Fromen, who has a joint appointment in biomedical engineering. Mimicking the complex structure and function of the lung in a lab setting is inherently challenging. The UD-developed 3D lung model is unique in several ways. First, the model breathes in the same cyclic motion as an actual lung. That’s key, Fromen said. The model also contains lattice structures to represent the entire volume and surface area of a lung. These lattices, made possible through 3D printing, are a critical innovation, enabling precise design to mimic the lung's filtering processes without needing to recreate its full biological complexity. “There's nothing currently out there that has both of these features,” she explained. “This means that we can look at the entire dosage of an inhaled medicine. We can look at exposure over time, and we can capture what happens when you inhale the medication and where the medicine deposits, as well as what gets exhaled as you breathe.” The testing process Testing how far an aerosol or environmental particle travels inside the 3D lung model is a multi-step process. The exposure of the model to the aerosol only takes about five minutes, but the analysis is time-consuming. The researchers add fluorescent molecules to the solution being tested to track where the particles deposit inside the model’s 150 different parts. “We wash each part and rinse away everything that deposits. The fluorescence is just a molecule in the solution. When it deposits, we know the concentration of that, so, when we rinse it out, we can measure how much fluorescence was recovered,” Fromen said. This data allows them to create a heat map of where the aerosols deposit throughout the lung model’s airways, which then can be validated against benchmarked clinical data for where such aerosols would be expected to go in a human under similar conditions. The team’s current model matches a healthy person under sitting/breathing conditions for a single aerosol size, but Fromen’s team is working to ensure the model is versatile across a much broader range of conditions. “An asthma attack, exercise, cystic fibrosis, chronic obstructive pulmonary disorder (COPD) — all those things are going to really affect where aerosols deposit. We want to make sure our model can capture those differences,” Fromen said. The ability to examine disease features like airway narrowing or mucus buildup could lead to more personalized care, such as tailored medication doses or redesigned inhalers. Currently, inhaled medicines follow a one-size-fits-all approach, but the UD-developed model offers a tool to address these issues and understand why many inhaled medicines fail clinical trials.
Saving the world, one yard at a time
University of Delaware professor Doug Tallamy has a simple mission: Encourage people to rid their property of invasive plants and replace them with native ones. One of the ways he's tackling it is through a concept called “Homegrown National Park,” a grassroots initiative he co-founded to offer a simple solution for the biodiversity crisis — the decline of a variety of animals, plants and numerous species. Tallamy, the TA Baker Professor of Agriculture and Natural Resources at the University of Delaware, is trying to encourage everyone to do their part to protect the planet. If invasive plants (which don’t belong in an area and can ultimately harm the ecosystem by taking away essential resources from other plants) grow out of control, then an area loses its biodiversity, the ability for multiple plant and animal species to function at once and create a rich ecosystem. Invasive species are prolific. For example, many invasive plants produce berries, which some birds eat. The birds then spread those seeds around. So, once invasive plants are in an area, they’re hard to get rid of. The idea is to replace them with native plants, which have historically belonged to a region and provide critical habitat for insects, birds and other creatures. It's an uphill climb, but Tallamy persists and is trying to save the world, one yard at a time. “Everybody has a responsibility of doing things that sustain their little piece of the earth, and there are a whole bunch of things one individual can do to help in that regard,” Tallamy said. What’s not so simple, however, is getting the Earth’s 8 billion people (or, at least, anyone with property) to do this. “We are trying to change the culture so that [replacing invasive plants with native ones] becomes the norm, not the exception,” Tallamy said. “We’re not getting rid of lawns. But we don’t need 44 million acres of them. There are now so many people on the planet that natural systems are not functioning the way they need to sustain us.” A snowball effect Much of our current plant culture revolves around colorful, aesthetically pleasing ornamental plants that don’t support the local food web. When they grow out of control, a local yard or larger region loses out on biodiversity. The natural world is all connected. For example, Tallamy said, if we lose pollinators like our native bees that transport pollen between plants, then we also lose most of our plants that produce flowers and fruits. It’s a snowball effect. “If that happens, the energy flow through our terrestrial ecosystems is almost totally disrupted, which means the food webs that support our vertebrate animals, our amphibians, our reptiles, our birds and our mammals would collapse and all those animals would disappear,” Tallamy said. “Without insect decomposers, the creatures that break down dead material, mostly plants, would rot and only bacteria and fungi would endure.” “Homegrown National Park” has generated a lot of buzz for Tallamy, who received recognition for it in October by the Massachusetts Horticultural Society. The MHS awarded Tallamy with its highest honor, the George Robert White Medal of Honor, for eminent service in the field of horticulture. Conservation in action Tallamy’s quest to “change the culture” on planting can be witnessed in the fall at UD. On a warm October afternoon, he and a group of students from the Introduction to Insect and Wildlife Field Studies (ENWC 165) course trudged out to UD Wetlands to curtail some pesky invasive plants native to Asia. Equipped with clippers, loppers and handsaws, they walked behind Worrilow Hall, part of the College of Agriculture and Natural Resources’ 350-acre campus, which includes the UD Wetlands, an area that was formerly a dairy cow pasture but transformed into wetlands in 2008 because pollution from the farm was reaching the local watershed. The wetlands were created because wetlands, by design, absorb nitrogen from runoff before it goes into waterways. They then release it as a gas into the atmosphere. But the UD Wetlands repeatedly deal with pesky invasive plants such as Porcelain-berry and Chinese elm. Over the years, UD students have stymied the species from overtaking the area. “See this? This is a good guy,” said Tallamy to the students as he held up a fallen branch. “You just want to get the Porcelain-berry off of it. They’ll grow back very well. But we want to nip [the Porcelain-berry] in the bud.” Taylor Kelly, a senior wildlife ecology and conservation major who took part in the invasive species removal, said Tallamy has helped her better understand the interconnectedness of various ecosystems. “Native plants provide so much value to our local pollinators, which add value to our local birds because they feed on pollinators, seeds, fruit and trees,” Kelly said. When native plants are in their natural environment, she added, it is a beautiful thing to see. Gardening with intention Tallamy, who began his teaching career at the University of Delaware in 1982, has published numerous research papers about entomology and written three books about native plants, insects and ecosystems, with a fourth book soon to come out. Lately, much of his career has revolved around public outreach. He often lectures across the country about native plants and their ecosystem value and is regularly quoted in outlets like The New York Times, The Washington Post and Natural History Magazine. “Dr. Tallamy is a rare scientist that is able to explain his work to everyone,” said Jake Bowman, UD professor of wildlife ecology and chair of the Department of Entomology and Wildlife Ecology. “His passion for the importance of native plants has driven a major shift in thinking.” Years ago, when Tallamy first set out to spread his messages about native plants, he anticipated a lot of pushback from horticulture enthusiasts who he thought might be resentful about being told how to choose their plants. Instead, Tallamy found that many actually embraced his ideas, including Delaware’s own Master Gardeners, a group of about 300 volunteer educators trained by UD Cooperative Extension. Among his supporters are Delaware Master Gardeners Karen Kollias, Brent Marsh and Judy Pfister, who each praised Tallamy for the impact he has had on how they garden. Kollias now “gardens with intention”— not for herself or her neighbors, but for the environment. “I was a gardener before,” she said. “Now I consider myself an ecological gardener.” After Marsh received a copy of Tallamy’s 2007 book, Bringing Nature Home, which talks about the link between native plants and native wildlife, Marsh became a Master Gardener and began planting native species in his Georgetown lawn. Today, native plants such as woodland sunflowers and oak trees adorn Marsh’s yard, and he is grateful for the value of native plants that he learned through Tallamy’s book. “Someday, maybe 20 years from now when I’m 100 years old, somebody's going to buy my house and they’re going to say, ‘Who planted all these oak trees?!’” Marsh chuckled. “Doug Tallamy changed my life.” As Tallamy has sought to simplify scientific knowledge with the general public, Pfister has utilized Tallamy’s approach to do the same. “He has a way of just making the whole thing a big circle, tying the need for a plant back to the need for a bird back to the need for a tree,” she said. Tallamy, who has been delighted by the fervor ignited by his native plants teachings, said the future of the Earth and its diverse ecosystems will in large part depend on how people treat their yards. “In the past, we asked our landscapes to do one thing, and that was, be pretty,” Tallamy said. “Now we have to ask them to do two things: be pretty and ecologically functional. That's the horticultural challenge of today.” But it’s one Tallamy believes can be achieved. Sometimes, he wishes he could speak to his 10-year-old self and tell the young boy to dig another pond for the toads to colonize. Restore. Conserve. Focus on keeping nature’s ecosystems intact, he would say. “We have to do both,” Tallamy said. “Yes, we have to conserve what’s out there, but we have to get in the mindset that we can really put a lot of it back.” Tallamy and Homegrown National Park co-founder Michelle Alfandari have created a database for people to type in their zip code and discover which native plants are best for their area.
Georgia Southern welcomes Georgia state leaders on Wexford Campus in Ireland
Georgia Southern University’s Wexford Campus in Ireland has been invigorating educational, civic, business and trade opportunities between Ireland’s southeast region and the state of Georgia since its establishment in 2022. The bicultural partnership has drawn the attention of state leaders in Georgia, prompting a recent visit to the international campus where Georgia Southern and its Irish partners welcomed the delegation. “We hosted legislators and leaders of industrial development and enterprise organizations,” said Howard Keeley, Ph.D., director of Georgia Southern’s Center for Irish Research and Teaching (CIRT). “These Georgia stakeholders believe that what Georgia Southern is doing in Ireland is important. One of the major concepts behind the Wexford Campus is that it’s a true campus, not just a study-abroad venue. So we’re pursuing several streams of activity. One is teaching and another is research. Another one is economic development, which includes internships and community engagement. We want to be in the community; therefore, to have leading constituents from a variety of industries in Georgia was very gratifying.” Among the attendees were U.S. Congressman Earl L. “Buddy” Carter; Georgia Department of Economic Development Commissioner Pat Wilson and five members of his senior staff, as well senior officials from electrical utilities, including Georgia Power; Trip Tollison, CEO of Savannah Economic Development Authority; Teresa MacCartney, chief operating officer for the University System of Georgia; and Georgia Rep. James Burchett (‘04), along with 10 additional members of the Georgia House of Representatives. “The main thing we wanted to do is show them what the student experience is like,” said Keeley. “We care about our students, and, using philanthropic funds, we’ve invested in a beautiful set of buildings, including one, built in 1886, that will house 50 students at a time. Each year, our goal is full capacity over six minimesters for a total of 300 Georgia Southern students. Historically a religious convent, that structure should open in spring 2026, after extensive remodeling. Many Georgia Southern students, including construction management and interior design majors, are gaining valuable professional skills by contributing to the endeavor.” The Wexford Campus already features the Learning Center, a historic administrative complex constructed in 1812 that has been transformed into a contemporary, high-tech educational space where students learn from local and international experts. They also present their research to peers and visiting Georgia Southern alumni while participating in high-impact experiential learning within the region. Visiting delegates were pleased to learn about the Honors College Global Scholars Program, which hosts 24 Honors College students who, taking an interdisciplinary approach, explore two themes for six weeks each spring in Ireland. This year, a prominent topic of study was sustainability in agriculture. One of Georgia Southern’s European research partners, South East Technological University Ireland, helped guide the students as they compared sustainability challenges along the coasts of Georgia and southeastern Ireland. The students drew on various research efforts, including important knowledge generated by Georgia Southern’s Institute for Water and Health. Similar integrated concepts also inform the summer and fall offerings. In 2024, they included two undergraduate global business courses, as well as the first Europe-based course from the MBA program at Georgia Southern’s Parker College of Business. One focus for the MBA students was Rosslare Europort, just south of Georgia Southern’s Wexford Campus, which has become Ireland’s fastest-growing port as multiple new direct routes to continental Europe have opened in response to Brexit. At a workshop facilitated by a top Rosslare Europort official, the MBA students explored international trade, logistics and supply chain management and the European regulatory environment. Spanning undergraduate, graduate and doctoral levels, the Wexford Campus has also provided courses in accounting, philosophy, sociology, geography, environmental biology, tourism and public health, among other disciplines. Shadowing Irish experts, population health science students from the Waters College of Health Professions focused on designing and delivering preventative-health programs, a critical matter in both Ireland and Georgia. “One of the metrics we use to measure success in Ireland is asking what makes it worthwhile for students to complete the course in Ireland as opposed to staying in the United States,” posed Keeley. “The bottom line is that we’re trying to provide a range of courses that look like Georgia Southern and that meet the degree needs, but also the employment needs in the state of Georgia. We’re always looking at how we can make our students more competitive, deepen their knowledge and give them as much hands-on experience as possible. This is really one of the things that we hope is a differentiator for us.” Notably, annual scholarships are available for the Honors College Global Scholars Program, Department of Political Science and International Studies students and Irish Studies students thanks to generous donations from alumni. In addition, philanthropic support has provided $1,000 to each participating student to offset the cost of transatlantic air travel. “The Wexford Campus’ directives exemplify Georgia Southern’s mission of providing holistic educational opportunities for our students to excel and grow,” said Annalee Ashley, Ed.D., Georgia Southern Vice President for External Affairs, Communications, and Strategic Initiatives, who participated in the trip. “Employers value global consciousness and intercultural skills when hiring, and our students who study abroad can enhance their skills, intellect and hireability in the marketplace. We are proud to serve Georgia and the entire southeastern region in this unique way, and to be supported by the state of Georgia as the University moves toward an R1 designation.” Beyond the campus, the group explored Johnstown Castle, an environmental and agricultural research center and heritage venue, as well as the Dunbrody Emigration Experience Center, whose newest permanent exhibition, Savannah Landing, is based on research by Georgia Southern students. The work highlights more than 170 years of historical ties that connect Savannah and Wexford, where hundreds boarded ships and crossed the Atlantic Ocean to arrive in Georgia’s coastal city in the mid-19th century. The centerpiece project, which was celebrated by the Irish prime minister at a ribbon-cutting in August, was made possible by $832,000 in research-grant funding, secured by the Dunbrody Center and Georgia Southern’s Center for Irish Research and Teaching. “Our guests got to experience history and understand the unique story that connects County Wexford to Savannah and, by extension, the state of Georgia,” noted Keeley. “Furthermore, they were able to see more than three-quarters of a million dollars of investment in Georgia Southern student work. That was super exciting.” The legislative group also met with Georgia Southern’s Irish partners, who shared what this relationship means to the people of Wexford and its hinterland, Southeast Ireland. “We invited all the players onto the field to strategically advance themes of education, economic development, and civic and cultural engagement,” said Keeley. “I believe they concluded that Ireland is a fit. It boasts a thriving economy that is modern, global and innovative. It’s the youngest economy in Europe in terms of workforce, and Ireland is one of the biggest investors in the U.S. economy.” Georgia Southern leadership and local Irish legislators, including four members of the Irish House of Representatives, Senator Malcolm Byrne and members of Wexford County Council, hosted Georgia’s VIPs with open arms. “They wanted to rally around us in the way that a family will rally around you,” said Keeley. “They couldn’t have done more. They totally rolled up their sleeves. It was a complete partnership hosting, and we were able to demonstrate that our network is so solid.” Wexford County Council leader Pip Breen shared opportunities for deeper connections with the Georgia delegation through the Irish nonprofit TradeBridge. Established in 2018, the entity facilitates trade and investment between the southeastern regions of Ireland and Georgia by developing new export markets and job creation opportunities. The trade corridor opens doors for southeastern Irish companies to establish a supportive base in southeastern Georgia, while also creating similar coordinates for companies based in southeastern Georgia to enter the European Union marketplace. Keeley, who was awarded the Presidential Distinguished Service Award for the Irish Abroad from the Government of Ireland in 2023, is a board member. “Georgia Southern’s footprint in southeastern Ireland is an important one for students and for the state of Georgia,” said Ga. Rep. Burchett. “The strides they are making not only allow students to participate in research in engineering, coastal sustainability, history and other important areas of study, but they also directly drive trade and investment opportunities between the southeastern regions of Georgia and Ireland. This was an amazing visit and we value our friendships within the Irish community.” Following the event, Burchett returned the hospitality with an invitation for Wexford County Council members to be recognized in person on the floor of the Georgia General Assembly in March 2025. “They very enthusiastically accepted the invitation,” Keeley shared. “I think when you’re involved in education, when you’re doing business and when you’re building out opportunities, the most important single thing is friendship and like-mindedness. You cannot achieve anything otherwise. There has to be this human-to-human connection. There has to be genuine mutual respect and mutual affection, and that was just in spades.” Georgia Southern’s Wexford Campus was featured on the national Irish TV program, “Nationwide.” You can see it here: Looking to know more, then let us help.

Humans have long taken inspiration from the natural world. From the indigenous cultures of the world who understand and utilize the properties of plant and animal products, to Leonardo da Vinci’s “flying machine” sketches inspired by his observations of flying birds, humankind has often looked to nature to help solve its problems and drive innovation. With rapid scientific advancements of the 19th and 20th centuries, and the exponential growth of sustainability practices over the last quarter century, the concepts of bio-inspired design and biomimicry have been increasingly pursued across myriad disciplines of study and implementation. Alyssa Stark, PhD, associate professor of biology at Villanova University, is one of the “boots-on-the-ground” researchers in pursuit of nature’s solutions to human problems. She recently took the time to chat with us about these fields, her research interests and the future of biomimicry. Villanova PR: We sometimes hear the terms “bio-inspired design” and “biomimicry” used interchangeably. Are they the same concept? Alyssa Stark: I see those as two different things. Bio-inspired design is when we are looking at an organism and see that it’s doing something that we want to emulate as humans. I work with animals that have unique adhesive properties. I ask questions like: Can we see that? Can we build it? Can we transfer that information, those ideas, those principles – it could be chemistry, physics, biological structure – and make something useful for us? That is also true with biomimicry, but the big difference for me is that we're keeping in mind the sustainability components. The natural world is not polluting. If we're using this biomimicry lens, how do we learn from nature to make products or solve problems in a sustainable way, keeping in mind the specific environment in which we are located? As an example, we wouldn't use a heavy water process if we were in the Arizona desert, instead we should look to our immediate surroundings to solve problems. PR: It seems the work going on in this field really takes a unique level of interdisciplinary collaboration. What types of different professionals are working in biomimicry? AS: It really pulls together biologists, engineers, physicists, chemists, even design artists and businesspeople. I've worked with a lot of different businesses that want to have sustainability in their company at broad levels by using biomimicry. They are not motivated by making a cool product, but realizing it actually saves them money if they think about their whole company in a biomimetic perspective. There are people who work on the social side of biomimicry, helping these companies completely restructure themselves to be more efficient and more time and money sensitive, without ever making a product. But of course, products are a huge part of it, too. And to make that happen, all of those professions, and more, are vital and active in this space. PR: In terms of products, what are some of the most successful examples of biomimetic designs being implemented? AS: A classic one is a building in Africa that doesn't have any air conditioning units because it has a series of vents like a termite mound. Or the bullet train being shaped like a kingfisher’s beak. One scientist found that whales have bumps on their fins, which you might think is not hydrodynamic. But as it turns out, it actually cuts through water more efficiently by creating little vortices. This concept was then applied to wind turbines. There are many examples of biomimicry actually working and being used. My mind is blown when I talk to an artist or designer about biomimicry because it's just wild the way they think. PR: Where does your overall work as a biologist fit into the world of biomimicry? AS: My hard science work is very much functional morphology – shape and structure of things and how they function. That includes behavior and their organismal interaction with the environment. I ask questions like: How do their structures function and perform? How sticky are they? How fast are they? How do they behave in their environment? What happens if they hit different challenges in their environment? My work kind of naturally fits well with biomimicry, especially for product development. I observe the natural world and then I start testing questions and predictions that I have about it, like figuring out how the heck this ant is sticking to this wet leaf. My results can then be applied directly. We have to first understand how these organisms work, and then others can run with it to try to put it to use. PR: What organisms do you work with and what about them are you studying? AS: I mostly study geckos, ants, and sea urchins and I just started working with some coral, looking at why some coral undergo bleaching, and some don’t. With sea urchins, we're also figuring out where their incredibly hard teeth are mineralized so we can understand it enough to try to mimic it. I like playing in that zone, because it still provides me a chance to do the hard science, but also talk to engineers and others and provide them information. With geckos, what I kind of broke open with my PhD thesis was that they have an adhesive that works in wet environments. Having a reusable adhesive that can work on skin, especially in the medical world, is a big problem and where most of my research lies. Think of a bug that you can’t pry off, but then it suddenly runs. How do these organisms move with such sticky feet? Figuring out how to make a reusable adhesive that doesn’t get dirty and can handle all these different environments is a difficult problem to solve. PR: How do you see this field evolving, especially as we strive for a greener, more sustainable future? AS: I would say the next step is the social levels of these big ecosystems. How do we build a city that functions like a rainforest or like a coral reef? Not just a product, but how do we actually shape our world by taking behaviors, processes, or systems that we see in the natural world to help us? Look at a pride of lions and their hierarchy, or what kind of feedback loops are there in an ant colony that allow them to give information back to their colony members quickly and share resources. I think that is the future of this field, and it’s an exciting future. *To learn more about Dr. Stark’s research and the field of biomimicry, click here to listen to a recent episode of NPR’s science show, “The Pulse.”
