I am the David L. and Elsie M. Dodd Professor of Finance at Columbia Business School and co-director of the Private Equity Program. I am also a Research Associate at the National Bureau of Economic Research (NBER), an associate editor at the Review of Financial Studies, Journal of Financial Economics, Journal of Corporate Finance, and Management Science.I study the financing of high-growth startups and financial intermediation via venture capital and private equity. My research aims to understand if and how financial intermediaries in private equity add value, and when they do, what that teaches us about financing and operational frictions companies face.
