Villanova Professor at the Forefront of Work to Tackle Quantum Threats
Securing Our Future Against Quantum Threats Security and privacy are values that everyone cherishes. No tech user wants their personal information getting into the wrong hands, which is why we have security measures in place to protect our private data: face ID to unlock our phones, two-factor authentication to log into banking apps and fingerprint technology to securely enter any system—from a computer to your front door. Encryption codes are used on each of these platforms to encode private data and allow only authorized users to access it. These measures are put in place to protect us, but new advancements in technology could soon challenge these secure systems that we have come to know and trust. Quantum computers are extraordinary machines capable of solving problems far beyond the scope of today’s standard computers. Although these computers are not commercially available, scientists harness their power for experimentation and data storage. Quantum computers excel in scientific development, but they may also prove to be a threat to existing technology that we use in our daily lives. Experts predict that by 2035, quantum computers could crack the very encryption codes that secure everyday transactions and data. Jiafeng Xie, PhD, associate professor of Electrical and Computer Engineering at Villanova University, is at the forefront of this battle, using his Security and Cryptography Lab to strengthen security measures against the threat of quantum computers. The Rise of Post-Quantum Cryptography Since quantum computer advancements are accelerating at an unprecedented pace, post-quantum cryptography (PQC) has emerged as a critical area of research and development. Scientists who study PQC are working to come up with new algorithms to encode our sensitive data, with a goal of being installed after quantum computers crack our current encryption systems. Without these new algorithms, once quantum computers break our current codes, sensitive data—whether personal, corporate or governmental—could be left vulnerable to malicious actors. The core problem of our current encryption system lies in the foundation of public-key cryptosystems. Public-key cryptography is a method of encryption where the user logs into a system using their own private “key”, and the back end of the system has a “key” as well. A “key” is a large numerical value that scrambles data so that it appears random. When a user logs in, their “key” can decrypt private information held by the public “key” in the system to ensure a secure login. This security method is safe right now, but these systems rely on mathematical principles that, while secure against classical computing attacks, are vulnerable to the immense processing power of quantum computers. At the heart of the vulnerability is Shor's algorithm, developed by MIT computer scientist Peter Shor in 1994. As Dr. Xie explained, “Shor invented an algorithm to solve prime factors of an integer that can supposedly run on a quantum computer. This algorithm, if run on a large-scale mature quantum computer, can easily solve all these existing cryptosystems' mathematical formulation, which is a problem." The realization of this potential threat has spurred an increased focus on the development of post-quantum cryptography over the past decade. The goal is clear: "We want to have some sort of cryptosystem that is resistant to quantum computer attacks," says Dr. Xie. In 2016, the National Institute of Standards and Technology (NIST) began the process of standardizing post-quantum cryptography. In July 2022, NIST selected four algorithms to continue on to the standardization process, where they are currently being tested for safety and security against quantum computers. The standardization process for these new algorithms is intensive, and two of the candidates that were announced for testing have already been broken during the process. Scientists are in a race against time to increase the diversity of their algorithms and come up with alternate options for standardization. The urgency of this shift to post-quantum cryptography is underscored by recent government action. The White House released a national security memo in 2022 stating that the U.S. government must transition to quantum-resistant algorithms by 2035. This directive emphasizes the critical nature of post-quantum cryptography in maintaining not just personal but national security. Villanova’s Security and Cryptography Lab Once a new algorithm is selected by NIST, it will need to be embedded into various platforms that need to be secured—this is where Dr. Xie’s Security and Cryptography Lab comes in. This lab is actively conducting research into how the newly selected algorithm can be implemented in the most effective and resourceful way. The lab team is working on developing techniques for this new algorithm so that it can be embedded into many different types of platforms, including credit cards and fingerprint technology. However, there are significant challenges in this process. As Dr. Xie explains, "Different platforms have different constraints. A chip-based credit card, for example, has limited space for embedding new encryption systems. If the implementation technique is too large, it simply won’t work.” Another arising issue from this research is security. During the application of this new algorithm, there's a risk of information or security leakage, so Dr. Xie is always on the lookout for developing security issues that could cause problems down the road. The Future of Post-Quantum Cryptography The implications of PQC are widespread and extend far beyond academic research. As Dr. Xie points out, "All existing cryptosystems, as long as they have some sort of function—for example, signing in or entering a password for login—all of these systems are vulnerable to quantum attacks." This vulnerability affects everything from banking systems to small-scale security measures like fingerprint door locks. The scope of this transition is massive, requiring updates to encrypted systems across all sectors of technology. His goal is to ensure that these new cryptographic systems are flexible enough to be applied to everything from small devices like credit cards and drones to large-scale infrastructure like data centers and military equipment. Although researchers are hard at work now, the future of post-quantum cryptography is not without uncertainties. Dr. Xie raises an important question: "When quantum computers become available, will the algorithms we develop today be broken?" While the newly developed algorithms will theoretically be secure, vulnerabilities can emerge when implementing any kind of new security system. These potential vulnerabilities highlight the importance of conducting this research now so that the new algorithms can go through intensive testing prior to being implemented. Despite these challenges, Dr. Xie emphasizes the importance of being prepared for this new reality. "Society as a whole needs to be prepared with this kind of knowledge,” he says. “A new era is coming. With our current security systems, we need to have revolutionized change. On the other hand, we should not be panicked. We just need continued support to do more related research in this field.” More extensive research is required to ensure that our privacy is protected as we enter a new era of quantum computing, but labs like the Security and Cryptography Lab at Villanova are a step in the right direction. Although the “years to quantum” clock is ticking down, researchers like Dr. Xie are well on their way to ensuring that our digital infrastructure remains secure in the face of evolving technological threats.
Aston University is leading a new £5.5 million EU research project Will focus on converting fibre-optic cables into sensors to detect natural hazards Could identify earthquakes and tsunamis and assess civil infrastructure. Aston University is leading a new £5.5 million EU research project to explore converting existing telecommunication fibre-optic cables into sensors which can detect natural hazards, such as earthquakes and tsunamis, and assess the condition of civil infrastructure. The project is called ECSTATIC (Engineering Combined Sensing and Telecommunications Architectures for Tectonic and Infrastructure Characterisation) and is part of the Horizon Europe Research and Innovation Action (RIA), which aims to tackle global challenges and boost the continent’s industrial competitiveness. Converting telecom fibres into sensors requires new digital signal processing to overcome the limited data storage and processing capabilities of existing communication networks. To address this the project will use localised, high performance digital processing that will integrate artificial intelligence and machine learning. The researchers’ goal is to minimise algorithms’ complexity while providing extremely accurate real-time sensing of events and network condition. The new laser interrogation and signal processing technologies will be tested using existing fibre optic networks, including those underwater, in cities, and along railway infrastructure to assess their potential. Delivered by a consortium of 14 partners across seven countries, from academic and non-academic sectors, the research will start in February 2025 and will last three and a half years. The Europe-wide team will be led by Professor David Webb who is based in the Aston Institute of Photonic Technologies (AIPT). Professor Webb said: “There are more than five billion kilometres of installed data communications optical fibre cable, which provides an opportunity to create a globe-spanning network of fibre sensors, without laying any new fibres. “These traverse the seas and oceans - where conventional sensors are practically non-existent - and major infrastructures, offering the potential for smart structural health monitoring.” Professor Webb will be joined by fellow researchers Professor Sergei Turitsyn, Dr Haris Alexakis and Dr Pedro Freire.

Putting a price tag on environmental projects
Unlike a grocery store, the goods and services in the environment — think clean water, tree cover, or flood control — don’t come with a price tag. Researchers in the University of Delaware Department of Applied Economics and Statistics have received a $1.5 million grant to assess the value of what is gained or lost from environmental projects. The three-year grant from the U.S. Army Engineer Research and Development Center, the chief research and development center for the federal environmental engineering agency U.S. Army Corps of Engineers, will pave the way for UD environmental economists to develop a web-based platform to help the Corps. The research team is led by Maik Kecinski, associate professor in the Department of Applied Economics and Statistics and also includes department colleagues Kent Messer and Martin Heintzelman, as well as three graduate researchers. The team will create an online platform to help the Corps estimate the monetary value of the ecosystem impacts through its ongoing and proposed projects across the U.S. Kecinski said many of the Corps’ projects involve natural resources, such as building dams or restoring rivers. Those projects require labor hours and equipment, each with a market value. “But the big piece the Corps doesn’t have is what is the environmental value that’s created or lost through these projects?” Kecinski said. The project came about after ERDC representatives visited UD in 2023. Kent Messer, Professor of Applied Economics, presented research about behavioral aspects around water quality and conservation and learned about ERDC’s research needs. Messer said that the big takeaway from those discussions was that ERDC was interested in having a platform to show the ecosystem services value of its projects. “So that was an exciting opportunity to connect and partner with them on the development of a tool that could help them in this regard,” Messer said. Messer said the opportunity to work with the Corps to assess its projects nationwide is “huge” for the University and for UD’s College of Agriculture and Natural Resources. “It speaks enormously to our college’s prominence in environmental economics issues,” Messer said. Martin Heintzelman, chair of UD's Department of Applied Economics and Statistics, said the project will help raise the profile of the department. “This is really in our wheelhouse in terms of the kind of research we do,” Heintzelman said. “It’s a great opportunity for us to be applying research to policymakers, people who are going to use this work to make better decisions as they’re going about their work constructing, managing, and sometimes de-constructing water and related projects.” The researchers hope the web-based platform will play a role in policy and decision-making, helping the Corps make more informed decisions on environmental projects in the future. “One thing I hope is going to come from this is the choices we make today are going to create a better tomorrow. That’s what it is all about” Kecinski said.
Aston University develops novel bone cancer therapy which has 99% success rate
Bioactive glasses, doped with gallium developed to create a potential treatment for bone cancer Lab tests have a 99 percent success rate of killing cancerous cells Method could also regenerate diseased bones. Bioactive glasses, a filling material which can bond to tissue and improve the strength of bones and teeth, has been combined with gallium to create a potential treatment for bone cancer. Tests in labs have found that bioactive glasses doped with the metal have a 99 percent success rate of eliminating cancerous cells and can even regenerate diseased bones. The research was conducted by a team of Aston University scientists led by Professor Richard Martin who is based in its College of Engineering and Physical Sciences. In laboratory tests 99% of osteosarcoma (bone cancer) cells were killed off without destroying non-cancerous normal human bone cells. The researchers also incubated the bioactive glasses in a simulated body fluid and after seven days they detected the early stages of bone formation. Gallium is highly toxic, and the researchers found that the ‘greedy’ cancer cells soak it up and self-kill, which prevented the healthy cells from being affected. Their research paper Multifunctional Gallium doped bioactive glasses: a targeted delivery for antineoplastic agents and tissue repair against osteosarcoma has been published in the journal Biomedical Materials. Osteosarcoma is the mostly commonly occurring primary bone cancer and despite the use of chemotherapy and surgery to remove tumours survival rates have not improved much since the 1970s. Survival rates are dramatically reduced for patients who have a recurrence and primary bone cancer patients are more susceptible to bone fractures. Despite extensive research on different types of bioactive glass or ceramics for bone tissue engineering, there is limited research on targeted and controlled release of anti-cancer agents to treat bone cancers. Professor Martin said: “There is an urgent need for improved treatment options and our experiments show significant potential for use in bone cancer applications as part of a multimodal treatment. “We believe that our findings could lead to a treatment that is more effective and localised, reducing side effects, and can even regenerate diseased bones. “When we observed the glasses, we could see the formation of a layer of amorphous calcium phosphate/ hydroxy apatite layer on the surface of the bioactive glass particulates, which indicates bone growth.” The glasses were created in the Aston University labs by rapidly cooling very high temperature molten liquids (1450o C) to form glass. The glasses were then ground and sieved into tiny particles which can then be used for treatment. In previous research the team achieved a 50 percent success rate but although impressive this was not enough to be a potential treatment. The team are now hoping to attract more research funding to conduct trials using gallium. Dr Lucas Souza, research laboratory manager for the Dubrowsky Regenerative Medicine Laboratory at the Royal Orthopaedic Hospital, Birmingham worked on the research with Professor Martin. He added: “The safety and effectiveness of these biomaterials will need to be tested further, but the initial results are really promising. “Treatments for a bone cancer diagnosis remain very limited and there’s still much we don’t understand. Research like this is vital to support in the development of new drugs and new methodologies for treatment options.” Notes to Editors Multifunctional Gallium doped bioactive glasses: a targeted delivery for antineoplastic agents and tissue repair against osteosarcoma Shirin B.

100 Days at 100 Degrees - How are Big City's Handling it?
This summer was a scorcher. And for some residents living in places like Phoenix, Arizona - it feels like summer will never end. A recent Los Angeles Times piece titled: 100 days of 100-degree misery: A summer of relentless, oppressive heat across the West took a close look at how cities are coping with record breaking heat and heat waves that are stretching longer than three month durations. And when reporters are covering complicated topics like this - it's experts like UC Irvine's Amir AghaKouchak they seek out to help with question and coverage. Amir AghaKouchak studies how climate change and variability influence extreme events (flood/drought/heatwaves) and compound hazards. "The city’s disparity in climate resilience is even visible from neighborhood to neighborhood, Amir AghaKouchak, a UC Irvine civil and environmental engineering professor, said. More affluent areas are better protected from extreme heat with vegetation and shade, while poorer areas have less shade and air conditioning. While people can’t stop heat waves from happening, he added, they can prepare as best they can for the sweltering conditions. “[Having a water bottle] can be the difference between heat stroke or no heat stroke, especially for vulnerable populations,” AghaKouchak said.

Industry and researchers call for action to tackle climate impact of organic, carbon-based chemicals
Call led by members of Supergen Bioenergy Hub, based at Aston University They highlight that carbon-based chemicals cannot be decarbonised but can be defossilised They want a transition to renewable carbon sources such as biomass, recycled carbon, and carbon dioxide. Director of Supergen Bioenergy Hub, Professor Patricia Thornley Industry experts and university researchers have joined together to ask the government to address the climate impact of organic, carbon-based chemicals. While demand for fossil fuels as energy is expected to fall in the coming decades, the petrochemicals sector is set to grow significantly according to experts and is set out in a 2018 report by the International Energy Agency. Members of the Supergen Bioenergy Hub which is based at Aston University and the Biomass Biorefinery Network believe the issue has yet to receive proper attention and is calling for a strategy that addresses this key component of our greenhouse gas emissions. They want a move to a more circular economy, managing supply and demand levels and transitioning away from fossil feedstocks which are raw materials required for some industrial processes. In their paper Carbon for chemicals How can biomass contribute to the defossilisation of the chemicals sector? they highlight that carbon-based chemicals cannot be decarbonised but can be defossilised through a transition to renewable carbon sources such as biomass, recycled carbon and carbon dioxide. Many products in modern society contain carbon such as pharmaceuticals, plastics, textiles, food additives, cosmetics, and cleaning products. These chemicals are derived from fossil feedstocks, so they are classed as petrochemicals. As a result, they contribute to global greenhouse gas emissions and climate change. Carbon is embedded in organic chemical products and released when they break down at end-of-life, for example through incineration. To address the emissions from carbon in chemicals and accelerate the development of bio-based chemicals, the group want a cross-party consensus to support a sustainable chemical system. Director of Supergen Bioenergy Hub, Professor Patricia Thornley, said: “We need to consider the UK’s future feedstock and chemicals production and use, and how it relates to net zero, agriculture, environment, economy, trade, and just transition policy objectives. There are opportunities here for the UK to lead the way on sustainable chemical production, but we need to carefully plan a roadmap for the transition, that delivers opportunities around jobs and the economy as well as sustainable greenhouse gas reductions. “There is a definite role for biomass here. But it is essential that any future use of biomass in the chemicals sector is underpinned by rigorous, trusted, and enforceable sustainability governance to build confidence, deliver sustainability benefits, and minimise negative impacts. That requires improvements in sustainability governance and regulation. “We think there are real economic and trade opportunities by the UK accelerating sustainable chemicals. At the moment bio-based chemicals, and chemicals derived from other renewable carbon sources, are not being expanded in the UK because there are no explicit incentives that prioritise them over fossil-based production.” The group argues that the UK has significant academic and industrial research expertise to underpin the development of sustainable bio-based products and could be a global leader in bio-based products and sustainability governance. They believe that to date little of this has manifested as UK-based scale-up and manufacturing, whilst there are numerous examples of UK-led research being scaled up elsewhere. The paper was delivered at a webinar on 7 August.

National Institutes of Health award $1.827 million for research on collective cell migration
Priscilla Hwang, Ph.D., assistant professor in the Department of Biomedical Engineering at Virginia Commonwealth University, has received a National Institutes of Health grant for $1.827 million over five years. The award from the National Institute of General Medical Sciences will support Hwang’s innovative research project “Dissecting mechanisms of collective migration” and provide mentorship for student researchers from the high school to graduate level. Collective migration, where groups of cells move together in a coordinated manner, is critical for the successful development of tissues and plays a vital role in wound healing, metastasis, and other biological processes. Dysregulation in collective migration is often linked to developmental abnormalities and disease progression. Despite its importance, the mechanics and mechanisms driving collective migration remain poorly understood. The project is organized around three primary goals: Investigate the effect of biomechanical cues to activate leader cells and directional collective migration: Understand how biomechanical signals activate leader cells to guide the migration of cell groups. Elucidate which and how leader cell mechanics are responsible for leader cell development: Identify the specific mechanical properties and behaviors that enable leader cells to emerge and lead the collective migration process. Examine the role of cell junctional forces in collective migration: Explore how the forces at cell contacts contribute to the overall migration and coordination among cells. Hwang will leverage her expertise in 3D microphysiological systems to study collective migration in dynamic, physiologically relevant environments. Her work aims to uncover the mechanisms by which leader cells sense and respond to mechanical forces in their environment, driving the collective migration of cells. “Our understanding of collective migration, especially the mechanics and mechanisms driving this phenomenon, is very limited,” Hwang said. “Our proposal will significantly accelerate our progress toward a comprehensive understanding of collective migration and lay the foundation for advancing treatment for developmental abnormalities or diseases.” The NIH grant will also expand student research and mentoring opportunities. “This Maximizing Investigators Research Award (MIRA) only goes to the most highly talented and promising investigators, and Dr. Hwang is most deserving,” said Rebecca L. Heise, Ph.D., Inez A. Caudill, Jr. Distinguished Professor and chair of the Department of Biomedical Engineering . “The award will provide support for undergraduate and predoctoral research opportunities in this important area of fundamental research that has an impact on neonatal development, cancer, and fibrotic disease.” To ensure diverse perspectives are considered throughout the project, Hwang said students from diverse populations will be recruited, including underrepresented minorities, women, and first-generation college students. “Further, we will continue to share our passion for science with the community through developing hands-on outreach activities based on our research findings,” she added.
How vulnerable are US energy facilities
Earlier this month, alarm bells were ringing at the Justice Department after a Jordanian citizen was arrested for targeting and breaking into solar power facility farm in Florida. During that same time period, energy facilities in New Jersey and Idaho also came under attack. The attacks were politically motivated and have led national media outlets like USA Today to contact experts from Carnegie Mellon University to help explain the situation and break if all down. The Department of Homeland Security has issued warnings that domestic extremists have been developing "credible, specific plans" since at least 2020 and would continue to "encourage physical attacks against electrical infrastructure." Industry experts, federal officials, and others have warned in one report after another since at least 1990 that the power grid was at risk, said Granger Morgan, an engineering professor at Carnegie Mellon University. One challenge is that there's no single entity whose responsibilities span the entire system, Morgan said. And the risks are only increasing as the grid expands to include renewable energy sources such as solar and wind, he said. August 15, 2024 - USA TODAY Professor Granger's comments are startling as America's vulnerabilities to important infrastructure seem to be more exposed than ever.

Florida Tech, Kennedy Space Center to Study Waste Treatment in Space
Associate professor of chemical engineering Toufiq Reza has spent years researching sustainable waste conversion techniques on Earth. When Florida Tech offered him a sabbatical, he took the chance to learn what that conversion process looks like in outer space while further strengthening the university’s already deep ties to NASA. In Fall 2023, Reza became the first professor to leverage school funding to spend a semester at NASA’s Kennedy Space Center. He worked with Annie Meier, who leads a team developing ways to convert astronaut-generated trash into fuel during missions, known as in-situ resource utilization (ISRU). “I wanted to do something different that I haven’t done. I have been doing research in my field; I know who the players are,” Reza said.” I could have easily gone to a research lab at another university and continued my research. But I wanted to learn something new.” His sabbatical prompted a new partnership between NASA Kennedy and Florida Tech. This summer, they signed an annex to their existing Space Act Agreement which will allow Kennedy Space Center (KSC) and the university to conduct joint research regarding logistical waste treatment and ISRU. “At NASA, we want researchers who are doing something that could help us, that could be synergistic, and to not reinvent the wheel,” said Jose Nuñez, university partnerships and small sat capabilities manager at NASA Kennedy. “The goal is to find professors who can benefit the agency in an area that needs more research.” As part of the agreement, KSC will share raw materials, waste simulant samples and information such as gas composition data with Florida Tech. In return, the university will analyze and share findings, such as what useful products can be taken from trash-to-gas waste for use as plant nutrients, and evaluate value-added applications. “I will encourage students to work on some of their technologies, test them in our lab and vice versa. This is a massive thing,” Reza said. “We can learn from each other to help each other.” Already, Reza’s students have visited Meier’s lab, and Meier and her KSC team came to Florida Tech to present her research and visit the university’s research facilities. Meier’s goals are similar to Reza’s: Both researchers want to find sustainable ways to convert trash and waste into energy, materials and chemicals. However, the methods aren’t completely transferrable between the two different environments of Earth and space. On Earth, Reza explained, waste can be burned or stored in a landfill. Neither of those options are viable in space. “You cannot dig up the moon soil and start burying. There is no oxygen or air to actually burn it…there is no water,” Reza explained. Currently, astronaut waste, such as food packaging, clothing, hygiene items and uneaten food, is launched back towards Earth and incinerates on the way there. However, Meier is working to advance waste mitigation technology, which Reza got to see up close. One of her projects, the Orbital Syngas/Commodity Augmentation Reactor (OSCAR), mixes oxygen, heat and trash in a reactor, which burns the trash and collects the gas it creates. Over the course of the semester, Reza assisted in KSC’s Applied Chemistry Lab, where Meier’s research took place. He offered both expertise and extra hands, from helping measure samples to reading through literature. He also took note of innovative technology for potential new research ideas, such as potentially developing a way of protecting metal coatings in space using the tools he learned. Meier’s waste conversion technology is built for a space environment, but Reza said it is unlikely that her complete systems could be used for waste conversion on Earth. Just as water and oxygen are limited resources in space but are plentiful on Earth, vacuums are plentiful resources in space but are expensive to create back home. However, that doesn’t stop the researchers from seeking inspiration through the new partnership. “We can learn from them and then take a part of their technology and integrate it with ours to make our technology more sustainable and vice versa,” Reza said. “They can improve their technology by utilizing part of our technology as well. As Meier said, “I wanted to learn on the terrestrial side how we can infuse some of our technology, and he wanted to learn from us to grow into the space sector, so it was a really cool match.”
Saving Lives, One Device at a Time: Clinical Engineering
Behind every health care provider, or perhaps already in the palms of their hands, is a piece of equipment necessary to their patient’s health and survival. Modern medical treatment relies on complex equipment to keep patients alive and healthy during procedures and recovery. Take live-saving equipment such as telemetry monitors, MRI machines and ventilators as just a few examples. But what happens when all that equipment needs repair? Enter ChristianaCare’s clinical engineering technicians. This team of 35 employees — one of the largest clinical engineering teams in the nation — is responsible for overseeing the care, testing and repair of the roughly 50,000 pieces of medical equipment in use throughout the ChristianaCare system. The Clinical Engineering team is overseen by Director Blake Collins, MBA, CBET, CHTM, nationally recognized for excellence in the profession. He brings two decades of experience as a clinical engineer in the United States Navy, seven of which were served with the U.S. Marine Corps, to his role. His team has won numerous trade industry awards for its success as a “solutions provider” for the health system. "Think of health care as a triangle,” said Collins. “You have the patient, the provider and the equipment. You can’t have successful health care delivery without those three elements.” Begun in the 1970s as the hospital system’s “TV repair shop,” he joked, the Clinical Engineering department evolved dramatically after subsequent national developments in electrical safety testing and oversight for the care and functionality of medical equipment. ‘Everyone truly cares’ Today, the Clinical Engineering department maintains close to 50,000 pieces of medical equipment throughout the ChristianaCare system, including its three hospitals and all its imaging centers. “From thermometers to linear accelerators, MRIs, CTs — we manage all of it,” Collins said. Last year, the team completed 25,000 work orders, or roughly 2,100 per month. “We get to help people in so many different ways,” said John Learish, Clinical Engineering manager. Samantha Daws, Clinical Engineering supervisor, echoed the sentiment. “The Clinical Engineering Department within ChristianaCare is the most talented group of technicians I have ever had the privilege to work with,” she said. “Everyone truly cares about keeping the equipment working to ensure all caregivers have what is needed to provide quality health care to our community.” Saving lives, one device at a time What’s so important about what Clinical Engineering offers to ChristianaCare? In short: Anyone could need medical care at any time, and if medical equipment were out of commission or wrongly calibrated, lives would be at stake. Collins recalls a pivotal moment during his tenure in the Navy, when he needed an emergency appendectomy while stationed on board an aircraft carrier. “I was the only biomedical technician on the ship,” he said. “And the doctor doing the procedure asked me, jokingly, ‘Hey Collins, is this equipment going to work?’ “He was kidding, but it’s true that we never know when we or a loved one is going to end up under the equipment that we work on as engineers.” This experience gained new significance for Collins after successful open-heart surgery at ChristianaCare in 2022 — followed by his mother, who had the same procedure, also successfully, in 2023. “I had not one inkling or shadow of a doubt that the equipment was going to work fine,” he said. “You never know who will end up needing care. So we take it very, very seriously.” Icon in the field For his outstanding service as Director of Clinical Engineering at ChristianaCare, Collins was presented with the 2024 John D. Hughes Iconoclast Award from the Association for the Advancement of Medical Instrumentation (AAMI), a career-marking honor in health care technology management. The award recognizes innovation and leadership in the field; for Collins, it shows how well the Clinical Engineering team works together to deliver safe medical equipment across the ChristianaCare system. “Blake has been a relentless advocate for ChristianaCare,” read his nomination. “He has implemented numerous initiatives and processes to improve his department … and work smarter through the use of technology and automation.” The next time you see a ChristianaCare provider pick up an instrument or turn on a machine, think about the Clinical Engineering team — and rest assured that your equipment is ready to go.
