My research focuses on the social aspects of dishonest behavior, particularly how social image—how we are perceived and judged by others—affects different types of lies. I am also deeply interested in healthcare-related decision-making and the biases that influence these processes. 

In addition to my research, I teach Organizational Behavior to B.A. and M.B.A. students at the Hebrew University.
