Roxane has been involved in this project from the beginning, and is one of the lead investigators researching the impacts of wildfire exposure on psychological well being. For more information about Roxane, see: https://faculty.sites.uci.edu/rsilver/.

Amir AghaKouchak, PhD

Dr. AghaKouchak’s research focuses include hydrology and water resources, climate extremes, remote sensing, and stochastic modeling. In relation to this project, Amir’s team has investigated how the loss of vegetation from wildfires can contribute to quicker transitions between flooding and drought, and how heatwaves can amplify the size and frequency of fires.

Read More

Amir’s team has also contributed to a centralized fire dataset, called the Fire-Occurrence Database (FOD), which compiles various fire-related attributes, including the burned area and cause (e.g., lightning, arson, power lines, fireworks), allowing researchers to analyze patterns across different regions. Using this dataset to explore fire patterns in Lake County and surrounding areas, Amir’s team has identified trends such as an increase in the frequency of human-caused fires. For more about Amir, see: https://amir.eng.uci.edu/index.php.

For this project, Diego conducted focus groups with emergency managers, planners, and community members including seniors, low-income residents, Hispanic residents (including non-english speakers), and tribal groups to identify information gaps and behavioral responses related to wildfire preparedness among vulnerable groups in Lake County. For more information about Diego, see: https://www.sociology.msstate.edu/directory/dt1282.

Ben Leshchinsky, PhD

Dr. Leshchinsky’s research focuses on evaluating landslide hazards and slope stability. Ben has been involved in this project since the beginning and is focused on understanding the lifecycle of wildfire impacts to identify periods of elevated vulnerability for cascading hazards and the timeline for ecosystem recovery.

Read More

In particular, his team has investigated the impacts of wildfires, such as how fire contributes to erosion, debris flows, and landslide susceptibility in Lake County. For more about Ben, see: https://directory.forestry.oregonstate.edu/people/leshchinsky-ben.

Timothy D. Stark, PhD

Dr. Stark’s expertise is in Geotechnical Engineering, and he has been conducting research and teaching on the stability of natural and manmade slopes, dams, embankments, and earth structures for over 30 years.

Read More

For this project, he is studying the impact of wildfires on the stability of natural slopes with ongoing weather monitoring in burned and unburned regions. To learn more about this work, visit our Field Monitoring page. For more about Tim, see: https://cee.illinois.edu/directory/profile/tstark.

Tirtha Banerjee, PhD

Dr. Banerjee leads the Boundary Layers and Turbulence (BLT) Lab, leading research on wildfires, environmental flows, and biosphere-atmosphere interaction using a range of theoretical, numerical, and experimental techniques.

Read More

Tirtha also serves on the Science Advisory Panel of the Fire and Forest Resilience Task Force in the State of California. For this project, Tirtha’s team has focused on mapping Wildland-Urban Interfaces (WUI)—identifying wildfire ignition points and high-risk areas where wildfires are more likely to impact human communities. Using this updated WUI map, the team was able to identify previously overlooked low-density buildings at risk of fire in Lake County, providing a clearer picture of fire risk zones.
