Jeff Cai is the Patricia and George Scharpf Family Assistant Professor in Real Estate in the IT, Analytics, and Operations Department (ITAO). Jeff received his PhD in Statistics and Data Science from the Wharton School at the University of Pennsylvania. His research lies in the intersection of statistical learning and data-driven decision-making, with applications to revenue management, corporate governance, healthcare, and urban studies. A significant thrust of his research is on sequential decision-making (bandits, reinforcement learning), network analysis, model selection and post-selection inference. Notably, his work involves constructing inter-firm networks, such as dynamic equity investment networks of all 40 million firms in China, to examine network effects on corporate behavior and decisions.
Jeff is passionate about teaching and has been teaching a statistical learning course at different levels, from pre-college, undergraduates, graduates and MBAs, to executive education. At Mendoza, he teaches machine learning in urban analysis in spring semesters.
