Dr. Gina Tonn is a postdoctoral fellow at the Risk Center. Her research interests include risk analysis and management for natural hazards, resilient infrastructure systems, sustainable water resources management, and climate change adaptation. Her interdisciplinary research involves the application of systems analysis methods in conjunction with water resources and environmental engineering methods to improve the understanding and management of risks associated with natural hazards in a changing climate. Gina’s professional experience in environmental and water resources engineering includes floodplain modeling, mapping, and management, stormwater design, and cost-benefit analysis. Gina received her Ph.D. in Geography and Environmental Engineering from Johns Hopkins University where she was an IGERT Water, Climate, and Health trainee. She earned a B.S. in Biological Systems Engineering from Virginia Tech with a concentration in Land and Water Resources Engineering and an M.S. in Management of Technology from Vanderbilt University.

At the Risk Center, Gina is currently working on a project to identify barriers and opportunities for improving the resilience of infrastructure systems through insurance, financial, and policy mechanisms. She is also working on analysis of flood insurance claims data to improve the understanding of how flood damages and insurance claims vary based on storm and geographic characteristics.
