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.

New report proves earning potential of EVs equipped with vehicle-to-grid technology

The University of Delaware, Exelon Corporation/Delmarva Power and collaborators have released a new report showing that electric vehicles equipped with vehicle-to-grid (V2G) technology can be profitable for private owners and businesses alike, with data from real electricity markets to back up the claims. The report is the outcome of a pilot program announced in 2024 by UD, and completed at the offices of Delmarva Power, which is part of Exelon Corporation, to confirm the value of V2G services to the grid. Among the key findings: the collaborators report that a V2G-enabled passenger electric vehicle (EV) could earn as much as $3,359 per year, based on 2021-2025 market prices, for storing and supplying energy to the electric grid during times of need, otherwise known as providing grid services. Heavier vehicles, such as fleet vehicles, delivery trucks or school buses, could earn over $9,000 per year, per vehicle. That’s a powerful income generator, given that privately owned vehicles are parked 96% of the time, on average, in the United States. Company fleet vehicles — even those operating 40 hours per week — remain stationary 75% of the average work week. The pilot, which included collaborators Ford Motor Company, the region’s electric grid operator PJM Interconnection, and aggregator Nuvve Corp., was tested using a small fleet of Delmarva Power EVs retrofitted with the bidirectional charging technology and a new advanced communications standard. The term “bidirectional charging” means that the V2G technology enables electric vehicle batteries to store extra energy from the electric grid when there is a surplus and to discharge that energy back to the grid when it is needed. In this way, V2G-enabled EVs can help the grid stay balanced, strengthening grid resilience and reliability, especially during peak demand and extreme weather events. New PJM rules allow properly certified EVs to provide this balancing and be paid for it — and the pilot proved they can meet these requirements and be paid for the service. For UD Professor Willett Kempton, who invented the V2G technology with colleagues at the University nearly 30 years ago, it’s a pivotal moment. “Whether it could scale cost-effectively was an open question, and we’ve proven that it can — with the right combination of policies, standards and technology,” said Kempton, professor of marine science and policy. For businesses such as Exelon, the report makes clear that V2G technology can help offset the cost of fleet electric vehicles while supporting the electric grid. This is because when the batteries in the parked fleet vehicles are aggregated together, they can function as a virtual power plant. The result is energy storage and supply that is available to the electric grid significantly faster than other conventional power resources, with virtually no wait times needed to power up or down. Unlocking a parked vehicle’s earning power Since Kempton and colleagues pioneered the innovative V2G technology, UD researchers have kept the charge going, accelerating progress on everything from V2G technology development to new automotive communication standards (called LIN-CP) for electric cars. They have advanced policy innovations at the state and federal level to overcome barriers in widespread adoption by enabling V2G technology to compete in electric markets, too. The recent pilot with Exelon/Delmarva Power and others also revealed that the EV batteries used for V2G remained fully functional after a full year of market operation — with no measured reduction in battery health — all while providing pollution-free power. “Something that might not be obvious to everyone is that these payments are not a subsidy; these EVs are earning money by competing with legacy generators, which is novel in a lot of ways,” said Kempton. “And when you’re participating in the market instead of a fuel-burning generator, you’re also reducing pollution.” This makes the technology both economically smart and functionally sound in a world where the electric grid is expected to include more renewables in the coming years. Kempton explained that most U.S. planned future electricity generation is scheduled to come from wind and solar. This will create greater fluctuation in the electric grid, which means more storage for energy surpluses will be needed. That’s where V2G can help, Kempton said. According to Brian Derr, senior analyst, Exelon Technology and R&D, insights from the pilot will inform future deployments and support the company’s broader strategy to enable the clean energy transition while maintaining reliable service for the communities it serves. “By leveraging existing assets in new ways, Exelon is positioning itself to build a more flexible, resilient and customer-focused energy system,” said Derr. Accelerating progress toward a V2G industry Next steps to expand the V2G industry to support the grid will require mass manufacturing to scale up the number of individual cars or fleets that are participating and earning money, Kempton said. Until now, changes to V2G-enabled vehicles have been done by retrofitting existing EVs to accommodate the V2G technology. Now with lower-cost standards and realistic market revenue values that can be expected, Kempton is looking at how this becomes adopted in many cars and many charging stations. “We’ll need at least a few car companies and charging station companies to mass produce this V2G equipment, and to deploy the technology into vehicles in the factory,” Kempton said. “If it is designed in, and mass produced, it’s incredibly cheap, especially when you compare it to the potential yearly revenue.” At UD, faculty and students continue to play a large role in the work aimed at bringing a fully functioning V2G industry to fruition. Kempton, Rodney McGee and recent graduates John Metz and Catherine Gilman, for example, are focused on policy changes and standards to allow V2G-enabled electric vehicles to provide grid services in more states. Such policies currently exist in Delaware and Maryland. Kempton would like to see this number grow. Meanwhile, UD postdoctoral researcher Garrett Ejzak and alumnus Go Charan Kilaru are focused on other aspects of the work. Ejzak is developing and testing these new EV technologies, and Kilaru is designing cryptography measures to ensure security protocols for V2G communications. Concurrently, UD students Colden Rother, Jude Borden, Lucia Paye-Layleh and Emmie Rossi are examining ways UD could electrify some of its campus fleets, under the advisement of UD’s Kimberly Oremus, associate professor of marine science and policy, economics, and public policy and administration.

University of Delaware biomedical engineer helps develop first immune-capable cervix-on-a-chip

A major breakthrough in biomedical engineering is changing how scientists study sexually transmitted infections (STIs) – and a researcher from the University of Delaware is at the forefront. Published in Science Advances, the study introduces the first immune-capable “cervix-on-a-chip,” a cutting-edge microphysiological system that replicates the human cervical environment. The platform allows researchers to observe how infections, the immune system and the vaginal microbiome interact in real time – something not previously possible with traditional lab models. Co-lead author Jason Gleghorn, associate professor in the College of Engineering, led the development of the model. His work highlights how engineering-driven approaches are advancing critical research in women’s health. By integrating engineering with biology, we can now simulate complex human systems more accurately and make these tools accessible to a wider range of researchers, Gleghorn said. The model recreates key features of the cervix using human cells, immune components and naturally occurring microbiomes within a dynamic system that mimics physiological conditions. When tested with infections such as chlamydia and gonorrhea, the platform revealed how protective bacteria can reduce infection risk – while imbalanced microbiomes can worsen outcomes. These findings could help accelerate the development of new therapies, including probiotics and other preventative strategies aimed at strengthening the body’s natural defenses. The research underscores the growing impact of the College of Engineering, where interdisciplinary collaboration is driving innovation across biomedical engineering and beyond. By combining expertise in engineering, microbiology and immunology, the team has created a powerful new tool that could reshape how STIs – and other complex diseases – are studied.

Artemis II and why repeated missions are essential to lunar success

Getting to the moon wasn’t a one-and-done kind of effort. It took repeated missions, each one teaching scientists and engineers something new, and each one making the next attempt a little smarter and a lot safer. That’s a big reason lunar success eventually became possible: people kept going back, gathering more data, fixing problems, and building confidence step by step. With all eyes on the Artemis II mission's final hours, University of Delaware space professor Bennett Maruca can talk all things space exploration and the race to the moon.  Have you ever wondered why Apollo 11 was named Apollo 11? It's because Apollo 1-10 were already taken! And mostly were fact-finding missions, with many barely leaving the ground, says Maruca.  Space program launches can cost billions of dollars. In order to ensure that they are successful, trial runs need to take place. Space travel leaves very little room for guesswork, and even small mistakes can have serious consequences. By launching multiple missions, experts could spot weaknesses, improve hardware, and make sure astronauts were better protected before taking on even bigger risks. In a way, each mission was like a rehearsal that made the final performances much more reliable. Maruca can reveal facts like this and more. He has been featured in multiple publications.
