Dr. Deepthi Kolady received her Ph.D. in Agricultural Economics from Cornell University, and M.Sc. in Agricultural Economics from University of Agricultural Sciences, Bengaluru, India. Dr. Kolady joined South Dakota State University (SDSU) as an Assistant Professor in 2016. Prior to joining SDSU, she worked at the World Bank, International Food Policy Research Institute, and Cornell University. Dr. Kolady’s research focuses on understanding producers’ and consumers’ decision making in the context of farming and food system to facilitate the development of a sustainable farming system and a healthy food sector. She is particularly interested in examining how agricultural producers and consumers respond to technological changes, markets, and policies. Her research addresses how consumer demand and preferences influence agricultural R&D investment, agricultural production practices, and food sector innovations. Dr. Kolady’s research efforts also include topics related to food and nutritional security.
