Aston University’s approach to a global challenge Across industries, companies face mounting pressure to cut carbon, improve resource efficiency, and contribute to the UN Sustainable Development Goals (SDGs). Yet many firms still struggle to move from vision statements to measurable action. At Aston Business School, Dr Breno Nunes, reader in sustainable operations management, is developing practical frameworks that help organisations embed sustainability at their core. His concept of 'sustainability fitness' captures how firms can build the capabilities they need to adapt, compete, and thrive in the transition to a net zero economy. “Many organisations want to be sustainable but struggle to operationalise what that means. My work is about bridging that gap — helping businesses translate strategies into practice.” — Dr Breno Nunes The sustainability fitness concept involves both meeting human needs and respecting environmental limits. While it can also be applied at the societal and individual level, Dr Nunes focuses on organisations, where capability building delivers the fastest, measurable change. Corporate sustainability fitness examines how a firm is able to survive and meet its own needs, while aligning itself to wider essential needs of society and operating within limits imposed by its surrounding natural environment. From research to real-world action Dr Nunes’ research examines how organisations design, implement, and monitor sustainability strategies across operations, supply chains, facilities, and product development. He is the main author of the book Sustainable Operations Management: Key practices and cases, which applies the issues of sustainability to all strategic decisions of operations. His work is already making a tangible difference, including international partnerships in Brazil, Canada, and the US, bringing cross-cultural insights into organisational transformation, as well as for various companies and organisations. In an Innovate UK Knowledge Transfer Partnership (KTP) with automotive supplier Metal Assemblies, Dr Nunes and Professor Alexeis Garcia Perez, professor of digital business and society at Aston University, are working to calculate and report the carbon cost of metal components used in car production, tackling one of the industry’s biggest sustainability challenges. The digitalisation of processes will allow Metal Assemblies to meet customers' requirements and position itself as a trusted and transparent supplier of low-carbon components. In another KTP with Brockhouse Group, a forging manufacturer in the West Midlands, Dr Nunes worked with Aston colleague Dr Muhammad Imran, reader in mechanical, biomedical and design engineering. Together they developed a sustainable manufacturing strategy centred on carbon reduction and process improvement. The work involved the development of an energy dashboard, allowing analysis of data on gas and electricity consumption. The project also included analysis of alternatives for energy recovery systems, and development of routines and procedures to improve the manufacturing process. As a result, Brockhouse group is more competitive to supply in non-captive markets. Dr Nunes has also been involved with a collaboration with Birmingham Botanical Gardens to integrate sustainability into policy and practice, expanding the use of business sustainability theories to nonprofit sectors. Sustainability can be embedded across different areas of organisations while seeking financial stability. As an environmental education charity, it is important to for Birmingham Botanical Gardens to 'practise what it preaches'. It was recently awarded almost £20m from various grants (including Heritage Lottery) in a capital project, thanks to having sustainability at the core of renovation plans. These projects highlight Aston University’s role in bridging academia, industry, and policy — ensuring research findings reach the boardroom as well as the factory floor. Key insights from the research Dr Nunes’ studies highlight several critical factors for turning sustainability from intention into measurable results: • Organisational capabilities are central to embedding sustainability. These include empowering sustainability “champions” (institutional entrepreneurs), supportive structures, superior technologies, and the ability to learn and balance economic, environmental, and social performance. • The tensions in implementing sustainability vary not just by function (supply chains, governance, innovation) but also by an organisation’s maturity level. • Start with the low-hanging fruit: tools like self-assessments, capability diagnostics, and learning games allow firms to act at lower cost before committing to full environmental impact assessments or formal reporting. • Collaboration between academia, industry, and policymakers accelerates real-world impact. Why this matters The stakes are high. Businesses worldwide are expected to reduce carbon emissions, demonstrate social responsibility, and remain competitive in a rapidly changing global economy. Aston University’s research shows that strengthening sustainability capabilities not only improves environmental outcomes but also boosts resilience and cost savings. In pilot projects, teams working with Dr Nunes have achieved up to 30% reductions in both cost and carbon emissions — proof that sustainability can drive operational performance as well as compliance. Looking ahead: expanding the Sustainable Growth Hub The next phase of Dr Nunes’ work centres on Aston’s Sustainable Growth Hub, which is being developed as a reference point for SMEs seeking sustainability solutions. In 2025, the Hub will: • Launch its first industry club cohort and expand its team. • Roll out new self-assessment tools to size sustainability needs and decarbonisation goals. • Introduce new learning formats and follow-up courses to Aston’s Green Advantage programme, alongside sessions to play a new corporate sustainability game. • Host events to bring together businesses, policymakers, and the wider sustainability management community. • Attract new research grants and publish results to share knowledge across both academic and practitioner circles. These initiatives aim to equip organisations not only to meet today’s challenges, but to anticipate tomorrow’s.

About Dr Breno Nunes Dr Breno Nunes is reader in sustainable operations management at Aston Business School and president of the International Association for Management of Technology (IAMOT). He serves as associate editor of the IEEE Engineering Management Review and has published widely on sustainability strategy execution and innovation. Aston University’s work in sustainable operations — shaped by researchers like Dr Nunes — is helping organisations worldwide move from ambition to action, building the 'sustainability fitness' needed for a net zero future.
American Nuclear Society names Lane Carasik, Ph.D., as one of its “40 Under 40”
Recognized as an emerging leader in the nuclear science and engineering field, Lane Carasik, Ph.D., assistant professor in the Department of Mechanical and Nuclear Engineering, was recently acknowledged by the American Nuclear Society as one of its top “40 Under 40.” “It is a huge honor to receive this acknowledgement from my professional community,” said Carasik. “I feel it is a reflection of the amazing nuclear engineering activities I’ve gotten the opportunity to pursue before and during my time at the VCU College of Engineering.” The list, featured in the most recent issue of Nuclear News magazine, celebrates young professionals who are driving innovation and shaping the future of nuclear science and technology. Created to spotlight a new generation of nuclear professionals, the “40 Under 40” program highlights those who are advancing technical fields, from advanced reactor deployment to AI applications and national security, while actively engaging the public, mentoring peers and advocating for nuclear’s role to achieve energy independence and security. “Dr. Carasik’s research efforts, together with his support for students and their own research goals, exemplifies the best qualities of the VCU College of Engineering,” said Arvind Agarwal, Ph.D., chair of the Department of Mechanical and Nuclear Engineering, “integrating research and teaching at the core of everything he does, from classroom and lab work to community outreach.” Carasik was selected for the “40 Under 40” from hundreds of candidates across the United States. Mentoring his first three Ph.D. graduates, Arturo Cabral, Connor Donlan and James Vulcanoff, is one of Carasik’s proudest achievements. He was also honored by the American Society of Mechanical Engineers (ASME) as a rising star in mechanical engineering in 2024 This builds off Carasik receiving the highly competitive and prestigious Department of Energy (DOE) Early Career Research Award ($875k split over five years) in 2023 to support his work on molten salt based fusion energy systems similar to Commonwealth Fusion Systems’ ARC technology. Carasik’s Fluids in Advanced Systems and Technology (FAST) research group, is a computational and experimental thermal hydraulics group focused on enabling the development of advanced energy systems and critical isotope production methods. Legendary physicist Enrico Fermi was an early inspiration to Carasik during his undergraduate studies. Fermi’s expertise mirrored Carasik’s interests, and the physicist’s impact on the field of nuclear engineering was motivating. As an established nuclear engineering faculty member, Carasik seeks to make a lasting impact on the field and the people in it. His ’s long-term goal is earning membership in the National Academies of Sciences, Engineering and Medicine.
Op-Ed: Stablecoin 'rewards' are a risk to financial stability
Congress has long recognized that stablecoins should not function as unregulated bank deposits. The intent of the recently enacted GENIUS Act is clear: to prohibit stablecoin issuers from paying interest or yield to holders, maintaining a distinction between payment instruments and bank deposits which are not only used for payment purposes but also as a store value. Yet loopholes have already emerged. Some crypto exchanges and affiliated platforms now offer “rewards” to stablecoin holders that work much like interest, potentially undermining the stability of the traditional banking system and constraining credit in local communities. Terminology matters. Credit card rewards are funded by interchange fees and paid to encourage spending — you earn points for using your card. Stablecoin “rewards” are different. They’re funded by investing the reserves backing stablecoins, typically in Treasury bills or money market funds, and passing that interest income to holders. You earn returns for holding the stablecoin, not for using it. Economically, this is indistinguishable from a bank deposit paying interest. When a platform advertises “5% rewards” on stablecoin holdings, it’s generally backing those tokens with Treasuries yielding about 4.5%, then passing that yield to users. Whether labeled rewards, yield or dividends, the function is the same: interest on deposits. Banks perform a similar activity — taking deposits, investing in loans and paying depositors a return — but face far higher costs, including FDIC insurance, capital requirements and compliance obligations that stablecoin issuers largely avoid. This dynamic has a precedent. In the 1970s and early 1980s, Regulation Q capped bank deposit rates at 5.25% while inflation and Treasury yields soared above 15%. Money market funds filled the gap, offering market rates directly to consumers. Deposits fled smaller banks, which lost their funding base, while large money-center institutions gained reserves. The result was widespread disintermediation, the collapse of the savings and loan industry and the farm-credit crisis of the 1980s. Stablecoin “rewards” risk repeating that history. Just as money market funds exploited the gap between regulated deposit rates and market rates, stablecoin platforms exploit the difference between what banks can profitably pay and what lightly regulated issuers can offer by passing through Treasury yields with minimal overhead. Some ask why banks can’t just raise deposit rates. The answer lies in structure. Banks operate under a fundamentally different business model and cost framework. They pay FDIC premiums, maintain capital reserves and comply with extensive supervision — costs most stablecoin issuers don’t bear. Banks also use deposits to make loans, which requires holding capital against potential losses. Stablecoin issuers simply hold reserves in ultra-safe assets, allowing them to pass through nearly all the yield they earn. To match 5% “rewards,” banks would need to earn 6% to 7% on their loan portfolios — an unrealistic target in today’s environment, especially for smaller community banks. The consequence is not fair competition, but a structural disadvantage for regulated depository institutions. The Consumer Bankers Association warns this loophole could trigger a massive shift of deposits from community banks to global custodians. Citing Treasury Department estimates, the Association notes that as much as $6.6 trillion in deposits could migrate into stablecoins if yield programs remain permissible. Because the GENIUS Act’s prohibition applies narrowly to issuers, exchanges and intermediaries may still offer financial returns under alternate terminology. This opens the door to affiliate arrangements that replicate the essence of interest payments without legal accountability. Those reserves don’t stay in local economies. The largest stablecoin issuers hold funds at global custodians such as Bank of New York Mellon, in money market funds managed by firms like BlackRock or — if permitted — directly with the Federal Reserve. When a community-bank depositor moves $100,000 into stablecoins, that capital exits the local bank and concentrates at systemically important institutions. The community bank loses lending capacity; the megabank or the Fed gains reserves. The result is disintermediation with a concentrated risk profile reminiscent of the money-market fund crisis. The Progressive Policy Institute estimates that community banks — responsible for roughly 60% of small-business loans and 80% of agricultural lending nationwide — could be among the most affected. In Louisiana, where local banks finance small businesses and family farms, that risk is especially relevant. If deposits migrate to unregulated digital assets, community-bank lending could tighten, particularly in rural parishes and underserved communities. Research from the Brookings Institution reinforces the need for regulatory parity. The label “rewards” doesn’t change the fact that these payments are economically interest. Allowing intermediaries to generate yield without deposit insurance or prudential oversight could recreate vulnerabilities similar to those seen during the 2008 money market fund crisis. To preserve financial stability, policymakers should move to close the stablecoin-interest loophole. Clarifying that the prohibition on interest applies to all entities— not just issuers — would uphold Congress’ intent. Regulators such as the Securities and Exchange Commission, Commodities Futures Trading Commission and federal banking agencies could also treat “reward” programs as equivalent to deposit interest for supervisory purposes. Stablecoins offer genuine efficiencies in payments, but unchecked yield features risk turning them into unregulated banks. History shows what happens when regulatory arbitrage allows competitors to offer deposit-like products without oversight: deposit flight, institutional instability and capital flowing away from community lenders. Acting now could help sustain stability, protect depositors and preserve the credit channels that support community lending — especially in states like Louisiana, where community banks remain the backbone of Main Street.
The Hidden Risks of Sports Betting
In a recent release from Cedarville University, Dr. Jared A. Pincin, Associate Professor of Economics, emerges as a prominent voice warning students about the hidden risks of sports betting. Pincin underscores that modern betting apps are intentionally designed to mimic mobile video games—fast, rewarding, and highly addictive—which makes them especially appealing to young adults and students. He emphasizes that while the appeal of quick wins is strong, the reality is that these platforms can erode both personal finances and educational opportunities. “The dark reality is that gambling is very addictive and can bankrupt people, strain marriages and destroy futures,” Dr. Pincin explains when describing the slippery slope that many young gamblers face. Grounded in his economic research and Christian ethics framework, Pincin adds another layer of concern: from a faith perspective, gambling exploits the desire for instant gain and distracts individuals from a more grounded trust in provision and purpose. He argues that with legalization expanding and betting apps readily available on smartphones, college students—not just athletes—are increasingly vulnerable to behaviors that can derail their academic trajectory and long-term goals. “Gambling preys on our desire for quick gain and distracts us from trusting God’s provision,” Dr. Pincin notes, bringing into focus the moral as well as the practical implications of sports gambling in a university setting. Dr. Jared Pincin's research interests explore the intersection of public choice economics with foreign aid as well as issues in sports economics. Pincin has published in popular publications such as The Hill, Real Clear Markets, Foxnews.com, and USA Today and scholarly journals such as Oxford Development Studies, Applied Economic Letters, and the Journal of Sport and Social Issues. View his profile here The release garnered a lot of attention - and substantial media coverage from outlets like ABC News and others.

Beyond the Repo Headlines: What the Liquidity Signals are Really Saying
In late October and early November 2025, usage of the Federal Reserve's Standing Repo Facility (SRF) reached elevated levels exceeding $50 billion at month-end -- the highest utilization since March 2020. Simultaneously, the Overnight Reverse Repo (ON RRP) facility has collapsed to approximately $24 billion, down from peak levels exceeding $2 trillion in 2023. This combination signals structural stress in U.S. money markets extending beyond seasonal factors. These two facilities serve opposite functions in the Fed's monetary policy framework. The SRF is an emergency lending facility where banks can borrow reserves overnight by pledging Treasury or agency securities as collateral, paying the SRF rate (currently 4.50%). It acts as a ceiling on overnight rates. The ON RRP works in reverse: money market funds and other institutions lend cash to the Fed overnight, earning the ON RRP rate (currently 4.30%). It provides a floor on rates. The depletion of ON RRP removes a critical shock absorber. When the facility held trillions in 2021-2023, it functioned as a deployable liquidity reservoir. During stress events, as repo rates in private markets rose above the ON RRP rate, money market funds would withdraw their cash from the Fed and deploy it into higher-yielding private repo markets. This automatic flow of liquidity would stabilize rates without Fed intervention. With ON RRP now depleted to $24 billion, this reservoir is empty. When liquidity shocks occur, there is no pool of cash to flow into stressed markets. Instead, all pressure falls directly on bank reserves, currently at approximately $2.8 trillion. The elevated SRF usage indicates that despite aggregate reserves appearing adequate, banks are unable to efficiently reallocate liquidity across the system. The core problem is that banks with surplus reserves face prohibitive costs to intermediating due to post-2008 regulations, particularly the Supplementary Leverage Ratio (SLR) and G-SIB capital surcharges. The SLR requires capital against all balance sheet assets, including reserves. For a large bank to lend $1 billion overnight, it expands its balance sheet by that amount, increasing SLR denominators and potentially triggering higher surcharge brackets. The capital costs of holding additional assets on the balance sheet often exceed repo market spreads, rendering arbitrage unviable. Banks with surplus reserves therefore park them at the Fed rather than lending to institutions that need them. Current conditions reveal that while dealer behavior around period-ends follows established patterns, the magnitude of rate effects has grown substantially. Recent Federal Reserve research documents that SOFR rose as much as 25 basis points above the ON RRP rate at recent quarter-ends, far exceeding the 5-10 basis point moves typical in 2017. The Fed's analysis attributes this to "growing tightness in the repo market and a diminishing elasticity of supply and demand" as reserves decline. Critically, the research shows that dealer quarter-end behavior -- reducing triparty borrowing and shifting to central clearing -- has remained "remarkably stable," yet rate impacts have intensified. This indicates the problem is not changing behavior but deteriorating underlying conditions. The pattern mirrors 2018-2019, when similar dynamics preceded the September 2019 crisis. Academic work from that episode documented that foreign banks reached minimum reserve levels while domestic G-SIBs maintained surpluses but declined to intermediate due to balance sheet constraints.¹ November 2025 differs critically from September 2019: the ON RRP buffer is now depleted. In 2021-2023, that buffer absorbed surpluses and prevented repo rate collapse. Its near-zero level means the system lacks this stabilizer precisely when QT has reduced reserves and Treasury issuance remains elevated. Additional liquidity pressure falls directly on reserves, leaving repo markets vulnerable to quarter-end dynamics, tax payments, or Treasury settlement volatility. Chairman Powell announced that QT will slow dramatically, with Treasury runoff ending while mortgage-backed securities continue maturing. However, this addresses only aggregate levels, not the structural issues driving period-end stress. The question remains whether current reserve levels are sufficient given elevated post-pandemic deposits, outstanding credit line commitments, tighter balance sheet constraints, and the expired Bank Term Funding Program. What do these signals indicate? Three interpretations emerge. The most likely is that quarterend and month-end rate effects will continue intensifying as reserves decline further, with the spread between SOFR and ON RRP at period-ends serving as a barometer of underlying tightness. Federal Reserve research suggests that as Treasury issuance continues and reserves decline, "the repo market is likely to tighten further and the effects of quarter- or month-ends on repo rates may grow, providing another potential indicator that reserves are becoming less abundant." This would manifest as larger SRF usage at period-ends and persistent elevated Fed facility usage, though system functioning would remain generally stable between these events. A more adverse interpretation sees a triggering event during an already-stressed period-end causing broader repo market seizure, forcing the Fed to resume asset purchases and confirming that meaningful balance sheet normalization is impossible under current structures. An optimistic interpretation requires regulatory reform -- SLR exemptions for reserves or changes to quarter-end reporting requirements -- to reduce incentives for balance sheet window dressing, though this appears politically unlikely. For banks, the implication is that reserve buffers need to be higher than pre-2019 benchmarks, and the ratio of demandable claims to liquid assets requires closer monitoring. For investors, continued volatility in short-term interest rates should be expected, particularly around periodends. The Fed's weekly H.4.1 release tracking SRF and ON RRP levels provides leading indicators. Money market fund flows have outsized impact as their allocation decisions directly affect system liquidity buffers. The transformation underway represents a fundamental shift from bank-intermediated to partially Fed-intermediated money markets. Post-2008 regulations strengthened individual bank resilience but broke private intermediation chains. The central bank now serves as both lender and borrower of last resort, with private markets unable to efficiently connect flows. September 2019, March 2020, March 2023, and November 2025 episodes demonstrate a pattern: reserves appear adequate until buffers thin, after which modest events trigger outsized disruptions. 1.

Motor vehicle crashes remain one of the leading causes of death among teenagers. For the youngest drivers, getting behind the wheel marks freedom but also comes with measurable risk. At the University of California, Irvine, Dr. Federico Vaca, professor and executive vice chair of emergency medicine, is determined to change that trajectory. “Driving licensure among our youngest drivers remains a major life milestone, and it allows for newfound freedom and opportunity for not only youth but their parents as well. At the same time, learning to drive and licensure come at a time when youth are rapidly moving through life with new transitions in school, with friends, and likely exposure to alcohol and drugs,” he says. “Our priority … is to examine the complexities of young driver behavior and to thoroughly understand crash injury risk and crash prevention among this special group of drivers.” Vaca’s work is at the intersection of health, transportation science and policy. A fellow of the Association for the Advancement of Automotive Medicine and a researcher at UC Irvine’s Institute of Transportation Studies, he previously served as a medical fellow at the U.S. Department of Transportation’s National Highway Traffic Safety Administration in Washington, D.C. His long-standing goal is to prevent the injuries he has seen and treated in emergency departments and trauma centers through rigorous research, using the findings to inform and advance evidence-based programs and policies that save lives on the road. Innovating safety science UC Irvine is home to a new hub for understanding and preventing crash injuries among young drivers, the Brain, Body & Behavior Driving Simulation Lab, founded by Vaca and his interdisciplinary team. At the heart of the B3DrivSim Lab is a high-fidelity, half-cab driving simulator capable of replicating real-world conditions with precision. It uses advanced software to design customized driving scenarios – from complex roadway environments to the inclusion of such human elements as distraction and fatigue – all while capturing real-time video and driving behavior as well as vehicle control metrics. This integration of medicine, behavioral science and engineering enables researchers to measure how developmental and socioecological factors shape driver decisions in unique and consequential ways. The B3DrivSim Lab also represents a growing mentorship ecosystem at UC Irvine. In mid-June, the facility welcomed Siwei Hu, a postdoctoral scholar who earned a Ph.D. in civil and environmental engineering, with a focus on transportation studies, at UC Irvine. Hu works closely with Vaca to combine engineering and modeling analytics with behavioral and crash risk insights. The half-cab driving simulator uses advanced software to replicate real-world conditions and design customized driving scenarios – from complex roadway environments to the inclusion of such human elements as distraction and fatigue – all while capturing real-time video and driving behavior as well as vehicle control metrics. Steve Zylius / UC Irvine From the lab to policy Beyond simulation, Vaca’s latest National Institutes of Health-funded study, separate from his lab’s work, takes this philosophy to the national level. His project, “Modeling a National Graduated-BAC Policy for 21- to 24-Year-Old Drivers,” explores whether lowering the legal blood alcohol limit for young adults could reduce alcohol-related crashes and deaths. “When you turn 21, at that very moment, the application of several alcohol-related prevention laws changes in the blink of an eye,” Vaca says. “Before that, the minimum legal drinking age and zero-tolerance laws are in place to protect young drivers from alcohol-impaired driving. Effectively, the second you turn 21, those prevention policies don’t apply, and you’re suddenly allowed to have a much higher blood alcohol concentration in your body that’s intimately tied to serious and fatal crash risk. It’s a very dangerous disconnect.” The study will use national crash data, behavioral surveys and system dynamics modeling to examine how a “graduated BAC policy” might bridge that gap, giving young adult drivers a safer transition into full legal responsibility and saving many more lives. Bridging science, education and prevention Earlier this year, Vaca and his B3DrivSim team joined prevention program educators, policymakers, engineers and law enforcement professionals in Anaheim at a Ford Driving Skills for Life event, part of a Ford Philanthropy-sponsored national effort teaching teens hands-on safe driving techniques – from hazard recognition to impaired-driving awareness. Speaking to more than 130 high school students and their parents from local and distant communities, Vaca emphasized the connection among driving, independence, opportunity and responsibility. That message aligns with his broader initiative, Youth Thriving in Life Transitions with Transportation, which introduces high school students to traffic safety and transportation science and their role in promoting health, education and employment in early adulthood. By linking research and real-world experience, the project empowers youth to see mobility as a foundation for opportunity with safety as its cornerstone. With overall young driver crash fatalities rising 25 percent nationally over the last decade and a 46 percent increase in fatal crashes where a young driver had a BAC of ≥ .01/dL, Vaca’s work represents a crucial step toward reversing that trend. Through a combination of clinical insight and prevention, transportation and data science underscored by community collaboration, he and his team are redefining how researchers and policymakers think about youth driver safety.
Heart valve developed at UC Irvine shines in early-stage preclinical testing
UC Irvine researchers designed and developed a minimally invasive replacement pulmonary heart valve. Created for pediatric patients, the device can be expanded as children grow, eliminating the need for multiple surgeries. The team successfully conducted laboratory and early-stage animal feasibility testing of the implant, crucial steps toward approval for human use. Irvine, Calif., June 23, 2025 — Researchers at the University of California, Irvine have successfully performed preclinical laboratory testing of a replacement heart valve intended for toddlers and young children with congenital cardiac defects, a key step toward obtaining approval for human use. The results of their study were published recently in the Journal of the American Heart Association. The management of patients with congenital heart disease who require surgical pulmonary valve replacement typically occurs between the ages of 2 and 10. To be eligible for a minimally invasive transcatheter pulmonary valve procedure, patients currently must weigh at least 45 pounds. For children to receive minimally invasive treatment, they must be large enough so that their veins can accommodate the size of a crimped replacement valve. The Iris Valve designed and developed by the UC Irvine team can be implanted in children weighing as little as 17 to 22 pounds and gradually expanded to an adult diameter as they grow. Research and development of the Iris Valve has been supported by the Eunice Kennedy Shriver National Institute of Child Health and Human Development; the National Heart, Lung, and Blood Institute; and the National Science Foundation. This funding has enabled benchtop fracture testing, which demonstrated the valve’s ability to be crimped down to a 3-millimeter diameter for transcatheter delivery and subsequently enlarged to 20 millimeters without damage, as well as six-month animal studies that confirmed successful device integration within the pulmonary valve annulus, showing valve integrity and a favorable tissue response. “We are pleased to see the Iris Valve performing as we expected in laboratory bench tests and as implants in Yucatan mini pigs, a crucial measure of the device’s feasibility,” said lead author Arash Kheradvar, UC Irvine professor of biomedical engineering. “This work represents the result of longstanding collaboration between our team at UC Irvine and Dr. Michael Recto at Children’s Hospital of Orange County built over several years of joint research and development.” Congenital heart defects affect about 1 percent of children born in the United States and Europe, with over 1 million cases in the U.S. alone. These conditions often necessitate surgical interventions early in life, with additional procedures required to address a leaky pulmonary valve and prevent right ventricular failure as children grow. The Iris Valve can be implanted via a minimally invasive catheter through the patient’s femoral vein. The Kheradvar group employed origami folding techniques to compress the device into a 12-French transcatheter system, reducing its diameter to no more than 3 millimeters. Over time, the valve can be balloon-expanded up to its full 20-millimeter diameter. This implantation method, along with the ability to begin treatment earlier in very young patients, helps mitigate the risk of complications from delayed care and reduces the need for multiple surgeries in this vulnerable population. “Once the Iris Valve comes to fruition, it will save hundreds of children at least one operation – if not two – throughout the course of their lives,” said Recto, an interventional pediatric cardiologist at CHOC who’s also a clinical professor of pediatrics at UC Irvine. “It will save them from having to undergo surgical pulmonary valve placement, as the Iris Valve is delivered via a small catheter in the vein and can be serially dilated to an adult diameter and also facilitate the future placement of larger transcatheter pulmonary valves – with sizes greater than 20 millimeters, like the Melody, Harmony and Sapien devices – if needed.” Kheradvar said that the next phase of preclinical testing of the Iris Valve is funded by the Brett Boyer Foundation, which is committed to supporting research into treatments for congenital heart disease. “We are actively engaged with the U.S. Food and Drug Administration to define and carry out the required experiments and documentation for first-in-human authorization of the Iris Valve,” Kheradvar said. “Our team is urgently advancing the Iris Valve through preclinical studies to enable its clearance for first-in-human use. This is a critical step toward providing toddlers – who currently have no viable minimally invasive treatment until they reach the 45-pound threshold – with a much-needed option.” First co-author Nnaoma Agwu, a biomedical engineering Ph.D. candidate at UC Irvine, said: “The development of the Iris Valve required a strong and knowledgeable team that understood the clinical and mechanical design requirements. This accomplishment would not have been possible without the collaboration of talented clinicians, veterinarians and engineers. With this milestone reached, we are rigorously advancing the Iris Valve’s development, setting our sights on human clinical trials.” Joining Kheradvar, Recto and Agwu as co-authors of the article in Journal of the American Heart Association were Daryl Chau, a recent UC Irvine master’s graduate; Gregory Kelley and Tanya Burney, both research specialists at UC Irvine, with Burney also affiliated with the Beckman Laser Institute; Ekaterina Perminov, a clinical veterinarian with UC Irvine’s University Laboratory Animal Resources; and Christopher Alcantara, a radiology technician at CHOC.

From classrooms to communities: Rethinking civic engagement in K–12 education
When national headlines focus on school board battles and political polarization, James Bridgeforth, assistant professor of educational leadership at the University of Delaware, is focused on what’s possible instead: building a more inclusive, participatory model of democracy through public education. His research in UD's College of Education and Human Development explores how community voice, equity and local leadership intersect to shape education policy – and how school boards can serve as vital engines for rebuilding public trust in government. "Despite the often sensationalized stories of chaotic school board meetings and the influence of more national "culture war" issues, I still believe that it's possible for people from different backgrounds, experiences, and points of view to come together to figure out how to best serve the needs of all of our children." – Bridgeforth Bridgeforth’s work centers on education governance, policy and leadership, with particular attention to how racism and anti-Blackness manifest in schools and policymaking spaces. His scholarship highlights the importance of inclusive decision-making, arguing that effective education policy must be representative of the diverse communities it serves. He recently published the report "Navigating Democracy in Divided Times" with co-authors on this topic. As part of his work with the Getting Down to Facts III project at Stanford University, Bridgeforth collaborates with researchers studying how to improve California’s TK–12 system and inform the next governor’s education policy agenda. His work documents the complex realities faced by local school board members – often minimally paid community leaders navigating contentious public discourse, social media pressure and limited resources. He notes that this research can be applied to school boards around the country. The next frontier: Youth civic engagement Over the next several years, Bridgeforth aims to deepen understanding of how schools can nurture young people’s civic skills and leadership capacity through participation in governance. One proposed project – "Strengthening Opportunities for Youth Civic Engagement and Student Voice in Educational Governance" – uses participatory action research to explore how student board member policies and engagement practices foster civic agency and democratic mindsets. This collaborative work brings together youth-led community organizations and education researchers to study how these experiences shape long-term civic behavior – from voting to public service. Why it matters Bridgeforth’s research arrives at a pivotal time for American democracy. As trust in public institutions erodes, local school boards remain one of the spaces where citizens can directly shape policy. His work points to a hopeful truth: democracy’s renewal may begin in classrooms, communities and the local school board meetings shaping them. For journalists covering education, race or civic engagement, Bridgeforth offers data-driven insight, lived experience and policy expertise – helping make sense of one of the most pressing questions of our time: How can we build systems that truly serve all students and communities? This work collectively demonstrates a number of promising opportunities to foster more inclusive, community-connected forms of governance, particularly in a time of eroding trust in government institutions." – Bridgeforth ABOUT JAMES BRIDGEFORTH Assistant Professor, College of Education and Human Development James Bridgeforth is an educator, researcher and policy advocate whose work focuses on community voice in education policy and the politics of educational leadership.

The missing AI revolution: Smarter leadership, not smarter machines, says workforce expert
Artificial intelligence has transformed industries, but its most overlooked potential lies in helping leaders themselves think more clearly and decide more effectively, according to Saleem Mistry, Associate Professor of Management at the University of Delaware’s Alfred Lerner College of Business & Economics. Mistry focuses on enabling leaders to be more productive, think clearly and make better decisions. Focusing on the leader, not just the organization Mistry’s work examines how leaders at every level can use AI to enhance productivity and decision-making. While most organizational conversations about AI focus on operational efficiency or customer service, he argues that the true frontier is leadership productivity. “Leadership productivity directly shapes organizational performance. AI can be transformative when it helps leaders think faster, decide better and regain the time they’ve lost to administration.” – Mistry As a professor of management and leadership, Mistry is often asked how AI will change the workplace. Those conversations usually revolve around automating workflows, not empowering leaders. Yet, as he notes, an MIT report found that 95 percent of generative AI pilots are failing — largely due to the absence of clear business use cases. That insight shaped his direction: leadership itself may be the missing use case. Having spent much of his earlier career in high technology, Mistry saw firsthand that innovation succeeds or fails based on how effectively leaders model new tools. Demonstrating practical applications Mistry recently analyzed the 2024-2025 U.S. Office of Inspector General reports on leadership challenges based. He analyzed each leadership challenge using three guiding questions: 1) Do the problems stem from leaders struggling with time, decisions or task management? 2) How might AI help? 3) Where could AI have the greatest impact? The results included: Executive Example (Amtrak): AI could power a real-time RACI dashboard to clarify accountability, track decisions and eliminate bottlenecks. Mid-Level Example (EPA): “Agentic AI” could cross-check allegations against verified data before termination decisions, preventing ethical and legal missteps. Supervisor Example (CISA): AI could scan incentive data for waste and anomalies, saving hours of manual review. Why it matters By automating repetitive, data-heavy tasks, AI gives leaders something they desperately need: time. Time to think strategically, coach teams and make better decisions. Mistry’s findings link AI adoption directly to mental well-being, arguing that improved decision productivity leads to improved organizational health. “Decision productivity is business productivity. Organizations that make faster, fairer and more informed decisions outperform those that don’t.” – Mistry Next steps: Building the framework for responsible AI leadership Mistry’s next milestone is to develop a set of leadership use cases that can be used by business leaders at all levels where AI can deliver the greatest impact. He is also developing frameworks for responsible AI adoption that help leaders determine when and how to deploy these tools ethically — across decision-making, communication, planning and task management. “AI won’t replace leaders,” Mistry concludes, “but leaders who learn to use AI effectively will outperform those who don’t.” ABOUT SALEEM MISTRY Associate Professor of Management Alfred Lerner College of Business & Economics Mistry’s research focuses on the future of work, with a particular emphasis on how individuals navigate workplace transitions. His research explores how people adjust to both minor and major changes in their careers, such as shifts in jobs, responsibilities, teams or entire organizations. A growing area of his expertise is the strategic use of artificial intelligence to enhance productivity for leaders, teams and human resource professionals. His research connects academic insights with practical applications, helping to shape how people and organizations adapt to an evolving professional landscape.

MCG scientists investigate arthritis drug’s impact on Alzheimer’s disease
According to the Alzheimer’s Association, more than 7 million Americans are living with Alzheimer’s disease, and one in nine of those people is 65 or older. Although that number is expected to grow, researchers at the Medical College of Georgia at Augusta University are making progress on studies that could turn into life-saving treatments. Qin Wang, MD, PhD, professor in the Department of Neuroscience and Regenerative Medicine at MCG and Georgia Research Alliance Eminent Scholar in neuropharmacology, recently published a study titled “The PKCι‑β‑arrestin2 axis disrupts SORLA retrograde trafficking, driving its degradation and amyloid pathology in Alzheimer’s disease,” in Molecular Degeneration, a leading journal in neurodegeneration. In the study, Wang and her team explored how certain proteins and enzymes interact in the brains of Alzheimer’s patients. Key players include the SORL1 gene, the PKCι enzyme and proteins SORLA, β‑arrestin2 and amyloid. SORL1 encodes SORLA, which helps regulate amyloid. Amyloid can form plaque in the brain, contributing to Alzheimer’s. People with the disease often have lower SORLA levels, which amplifies plaque production. “The goal is to increase SORLA levels in patients with AD. If we can boost it up, that would be great,” Wang said. “But if you want to know how to boost it up, you have to know how it is degraded, so that’s what our work is about – we’re trying to understand how its stability is regulated.” Wang’s research team found that PKCι can add a phosphate group to SORLA, which helps SORLA interact with β‑arrestin2. The PKCι‑β‑arrestin2 axis leads to SORLA degradation, reducing its levels and allowing amyloid plaques to grow unchecked, thereby worsening the disease condition. They discovered this by using biochemical methods and a mass spectrometer managed by Wenbo Zhi, PhD, at the Proteomics and Mass Spectrometry core lab at AU. “We conducted biochemical studies and found that SORLA can be phosphorylated. We identified the phosphorylation site and the interacting enzymes,” Wang explained. “Using the mass spectrometer with PKCι, we saw increased phosphorylation of SORLA at certain sites. Preventing that could stop SORLA degradation.” That’s where a rheumatoid arthritis drug called auranofin comes into play. “While it is an arthritis drug, it can also inhibit the PKCι enzyme,” Wang explained. The team conducted tests using Alzheimer’s mouse models and human iPS cells developed into neurons. For the mouse models, they treated the mice with auranofin for eight weeks, resulting in decreased amyloid levels, reduced neuroinflammation and improved cognitive function. Similar results were seen in human cells with increased SORLA levels and decreased amyloid levels. “A good thing about this is, because this is an FDA-approved drug, it’s ready to be tested in Alzheimer’s patients,” Wang said. “People often worry about drug safety because of long-term use in chronic diseases like Alzheimer’s, but, in this case, existing safety data for chronic use gives a good starting point for testing in Alzheimer’s patients. “I hope a drug company can pick that up for a trial with Alzheimer’s patients because we are trying to translate our bench work all the way to the bedside for treatment,” she continued. The study wraps up a five-year National Institute on Aging grant, a collaborative effort between Wang’s lab and the Kai Jiao, MD, PhD, lab in AU’s Center of Biotechnology and Genomic Medicine. Wang’s team is also working on other grant-funded Alzheimer’s-related projects and hopes to continue making advancements toward finding a cure for this debilitating disease. “All of our projects share the goal of finding a better treatment,” Wang said. “Related to this project in particular, we want to know how the SORLA protein works in different types of brain cells, given the brain’s complexity. Then we can determine how to specifically target that protein to develop more effective therapies.” Qin Wang, MD, PhD, researches the neuropharmacology and signaling mechanisms underlying neurological and psychiatric disorders.
