Los Angeles wildfires: Experts address health concerns and evacuation strategies

Jan 8, 2025

Major wildfires are once again raging in California, this time in Los Angeles County. According to news reports, they have so far been responsible for two deaths, 1,000 damaged structures and the evacuation of more than 30,000 residents. Experts from the University of Delaware's Disaster Research Center can comment on health impacts, evacuation strategies and how to manage pets and animals during disasters.

Below are three of the Disaster Research Center core faculty and the topics they can discuss related to the current wildfires:

Jennifer Horney, founding director of UD’s epidemiology program: Health impacts of disasters (mental and physical) as well as evacuation. Additionally, exposure to wildfire smoke which increases risk of respiratory infections; the scale of these fires during a very high period for these infectious diseases (flu, RSV, COVID) may also put pressure on public health and health care systems.

Tricia Wachtendorf, co-director of the Disaster Research Center and professor of sociology and criminal justice: Disaster donations, social vulnerability and evacuation.

Sarah DeYoung, associate professor of sociology and criminal justice: Pets and animals during evacuations.

Can AI save our oyster reefs? A team of scientists put it to the test

With global oyster populations having declined by more than 85% from historical levels, restoring and monitoring these critical ecosystems is more urgent than ever. But traditional monitoring methods aren’t cutting it. A team of researchers that included the University of Delaware's Art Trembanis have taken a new approach, testing an AI model designed to recognize live oysters from underwater images. The findings? The AI model, called ODYSSEE, was faster than human experts and non-expert annotators, processing in just 40 seconds what took humans up to 4.5 hours. But it wasn’t yet as accurate. In fact, the tool misidentified more live oysters than both groups of human annotators. Still, the team found that ODYSEE has real potential to monitor reefs in real time. Why does this matter? As climate change, pollution and overharvesting continue to pressure coastal environments, more precise and non-invasive monitoring tools like ODYSSEE could become essential to restoration efforts and environmental policy. Trembanis can discuss this new tool and its ability to identify live oysters without disturbing the reef. His expertise in oceanography, engineering and robotics expertise was key to the team's work. The results, published in the journal Frontiers, offer both caution and hope in the race to improve ocean monitoring with emerging technologies.

Will AI undermine or support writing and critical thinking?

As artificial intelligence reshapes the way we write and think, a central question emerges: Is AI helping or hindering our ability to engage in independent, critical thought? Joshua Wilson, professor of education at the University of Delaware, investigates this topic in a new paper that examines the risks of AI dependency and discusses the need for AI literacy in education. Wilson explores how AI impacts cognitive development through writing — highlighting both the promise and peril of AI-powered tools like ChatGPT. His expertise centers on how these tools interact with foundational models of writing and learning and what that means for education, workforce readiness and civic engagement. In his new paper, Wilson warns that while AI can support higher-order thinking by automating basic writing mechanics, it also risks eroding critical thinking if students and professionals come to rely on it uncritically. He is a leading advocate for AI literacy in education – training individuals not just to use AI, but to think with it. Wilson is available for interviews with reporters, particularly those covering the intersection of AI, education and society and investigating the risks of cognitive offloading in an AI-saturated world.

Fast-striking and unpredictable, tornadoes pose major challenges for emergency planners

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.
