At least 20 U.S. states have been hit with tornadoes – some of them deadly – over the past week. Experts from the University of Delaware's Disaster Research Center can speak to the difficulty of drawing up plans in advance of tornadoes, which can develop quickly and unexpectedly, as well as a variety of topics related to storm preparedness, evacuations and recovery.


Those experts include:


Jennifer Horney: Environmental impacts of disasters and potential public health impacts for chronic and infectious diseases. Horney, who co-authored a paper on the increase in tornado outbreaks, can talk about how impacts on the morbidity and mortality that result from tornadoes.


Tricia Wachtendorf: Evacuation decision-making, disaster response and coordination, disaster relief (donations) and logistics, volunteer and emergent efforts, social vulnerability.


James Kendra: Disaster response, nursing homes and hospitals, volunteers, response coordination.


Jennifer Trivedi: Challenges for people with disabilities during disaster, cultural issues and long-term recovery.


Sarah DeYoung: Pets in emergencies, infant feeding in disasters and decision-making in evacuation.


A.R. Siders: Expert on sea level rise and managed retreat – the concept of planned community movement away from flood-prone areas.

Pandemic deepened health gaps for people with disabilities, study finds

A new peer-reviewed study published in the American Journal of Preventive Medicine reveals that U.S. adults with disabilities experienced significant declines in preventive cardiovascular screenings during the COVID-19 pandemic — and continued to face cost-related barriers to care, even after accounting for economic disruptions. Using nationally representative data from more than 150,000 adults between 2019 and 2023, the study highlights how routine care like blood pressure, cholesterol and glucose screenings dropped most sharply for those with cognitive, physical, or multiple disabilities. Adults with disabilities were also more likely to report delaying or missing care due to cost. These findings underscore persistent health inequities and the urgent need for inclusive public health strategies, especially for populations already at greater risk for cardiovascular disease. Why it matters: Cardiovascular disease remains the leading cause of death in the U.S. Adults with disabilities face higher risks and more barriers to care — making consistent preventive screenings essential. This study offers the first detailed, post-pandemic national look at how different disability groups were affected, with implications for future policy and healthcare reform.

Food is medicine, and this professor has the research to prove it

For more than 20 years, Dr. Allison Karpyn has worked to understand and address food insecurity in America and beyond — studying how communities access healthy food, how policy shapes those opportunities and how local partnerships can make meaningful change. A professor in the University of Delaware’s College of Education and Human Development and co-director of its Center for Research in Education and Social Policy, Karpyn has published extensively on topics including food deserts, healthy corner store initiatives, school nutrition programs and strategies to bring farmer’s markets to underserved areas. Her work, which blends rigorous research with community-based implementation, has appeared in leading journals such as Pediatrics, Preventive Medicine and Health Affairs. Karpyn has also worked directly with nonprofit organizations, government agencies and retailers to pilot and evaluate programs designed to increase access to high-quality food in low-income neighborhoods. Her focus is on actionable, data-informed solutions to persistent challenges — from childhood hunger to structural barriers in the food supply system. Now, Karpyn’s expertise is being tapped as part of Delaware’s new Food is Medicine Committee, a statewide initiative under the Delaware Council on Farm and Food Policy. The committee seeks to connect nutrition and health care to improve outcomes, lower costs and strengthen local food systems — goals that align closely with Karpyn’s career-spanning mission. For journalists exploring food policy, hunger, public health and the future of food access, Karpyn is a key source of insight, research and real-world perspective.

Mental health risks spike for young LGBTQ+ men of color, new study shows

As Pride Month shines a spotlight on the progress and resilience of LGBTQ+ communities, it also serves as a reminder of the ongoing challenges — especially the toll that stigma continues to take on mental health. A new in Developmental Psychology study from the University of Delaware’s Eric Layland, assistant professor in the College of Education and Human Development, reveals just how urgent the need for tailored mental health support is — particularly for Black, Latinx and Afro-Latinx gay, bisexual and other sexual minority young men. Published during a time when national attention turns toward LGBTQ+ visibility, the study tracks the mental health trajectories of over 400 cisgender men between the ages of 18 and 29, focusing on how experiences of racism, heterosexism, or both — what Layland terms compound stigma — influence patterns of depression and anxiety. The results are stark: participants who experienced frequent racism and heterosexism across relationships and settings showed the earliest and most severe symptoms of anxiety and depression, with mental health challenges peaking during late adolescence and early adulthood. While symptoms tended to decline by age 24, these years — critical for education, identity formation and economic independence — were marked by emotional strain. "This study emphasizes how multiple sources of discrimination converge to impact the mental health of sexual minority men of color," Layland said. The research calls for early, culturally responsive mental health interventions that help young sexual minority men of color cope with stigma and build resilience. Layland’s team points to interventions that not only teach coping skills but also foster connection, celebrate cultural identity and create peer networks for support. Layland, who specializes in LGBTQ+ development and affirmative interventions, underscores the importance of systemic change as well.  “We need clinical and community resources that are adapted to address the intersecting discrimination experienced by sexual minority men of color, especially in their late teens in early twenties,” said Layland. Supported by the National Institute on Drug Abuse, the National Institute on Mental Health and UD, this study arrives at a crucial time for researchers, educators and community organizations working to create more inclusive and supportive environments. For journalists covering Pride, mental health, or intersectional equity, Layland’s work offers a powerful, data-driven look at what young LGBTQ+ people of color are facing — and how communities can act to change that story.  Journalists can reach Layland by clicking on his profile.
