Curriculum Vitae

Hortense Fong uses machine learning, econometric, and experimental methods to study how emotions impact consumer behavior. A distinguishing feature of her interests involves going beyond ML’s use in prediction to study how to incorporate domain-specific theoretic and managerial knowledge into ML systems and make them more interpretable. She also has a broader interest in questions at the interface of marketing and society (e.g., fairness).
 
Before joining Columbia, Professor Fong received a Ph.D. in Quantitative Marketing from Yale. She teaches the Marketing Analytics course.
