Dr. Casey Wichman is an applied microeconomist working on issues at the intersection of environmental and public economics. His research focuses on how people interact with the natural and built environment, and what that behavior reveals about the value of environmental amenities. His research spans water and energy demand, valuation of environmental resources and infrastructure, urban transportation, public goods provision, demand for outdoor recreation, and climate change. Methodologically, he relies on the application of program evaluation techniques, often using large micro-data sets, to estimate causal effects of environmental policies on economic behavior. 

Prior to joining Georgia Tech, Dr. Wichman served as the Research Director of the Energy and Environment Lab at the University of Chicago and as a Fellow at Resources for the Future, an environmental economics think-tank in Washington, DC. He received his Ph.D. from the University of Maryland in 2015, and his doctoral work earned outstanding doctoral dissertation awards from both the Association of Environmental and Resource Economists and the Association of Agricultural and Applied Economists.
