Isabelle Engeler is an Assistant Professor at IESE Business School. Prior to joining IESE in 2016 Isabelle was completing her postdoctoral research at New York University’s Stern School of Business and the University of St. Gallen.

Isabelle investigates positivity biases and their effect on people’s judgments, emotions, motivation, and behaviors in various domains such as consumption, pricing, and goal achievement. She examines people’s positivity when they compare themselves to others (self-other bias), in their attributions of current outcomes (self-serving bias), and in their representation of desired future outcomes (positive fantasies, optimism in predictions). A subset of her research focuses on topics related to de-biasing methods in survey research. Methodologically, Isabelle extensively uses field experimentation as a means to validate lab studies, but also to contribute to managerial practice and to develop authentic cases for the classroom. Her research style is one of cross-fertilizing theory, managerial problems, and teaching. Her research has been published in the Journal of Personality and Social Psychology and is regularly presented at leading conferences in the field.

Over the last several years, Isabelle has led many consulting projects for various consumer goods, governmental, or service industries in the US and Europe on issues including price strategy, behavioral pricing and framing, marketing strategy, positioning, or customer satisfaction measurement. Prior to joining the graduate program, Isabelle worked in the marketing department of Longines S.A., a Swiss watch company, and in the online trading industry with E-sider.com (TradeDirect).
