Dr. Habtamu Tilahun Kassahun joined the Institute for Choice in June 2015 as a postdoctoral Research Fellow in Choice Modeling. Dr. Kassahun current research focuses on developing new econometric models of choice behavior that recognize individuals adopt different strategies (Antecedent Volition). His research also focuses on applied microeconomics including environmental valuation and management, individual travel behavior and spatial-and-social interaction.

Kassahun has been leading a research project focused on the reliability of stated preference study addressing the valuation of land and environmental resources in urban and rural areas.
