I am the David L. and Elsie M. Dodd Professor of Finance at Columbia Business School’s finance division.  I research 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 faced by companies.  I am also a Research Associate at the National Bureau of Economic Research (NBER), associate editor of the Review of Financial Studies, associate editor at the Journal of Financial Economics, co-editor of the Journal of Economics & Management Strategy and Associate Editor at the Journal of Corporate Finance.  I edited the 2023 Special Issue on Private Equity published in the Journal of Corporate Finance.

I have taught venture capital and private equity finance at the undergraduate and masters level at Columbia Business School, California Institute of Technology, Wharton School, Carnegie Mellon University and University of California San Diego.  These courses include Entrepreneurial Finance (Columbia MBA), Venture Capital Finance (CMU MBA, Caltech), Private Equity Finance (CMU MBA) and Empirical Methods (CMU, Caltech PhD).
