Assoc. Prof. Eldad Yechiam

Behavioral Science and Management


Associate Professor Eldad Yechiam joined the Faculty of Industrial Engineering and Management at the Technion in 2005 as a Senior Lecturer in Behavior Sciences. Previously, he completed an M.Sc in Industrial Psychology and a Ph.D in Cognitive Psychology at the Technion, and was a postdoctoral fellow in Indiana University, Bloomington. Dr. Yechiam’s area of work is decision making, learning, and behavioral economics. His main contributions are in the study of cognitive assymetries that result from different incentive structures, individual differences in decision making, and cognitive enhancement.
