Short Bio

Hi! I am an an economist working on market design in the context of online marketplaces, and, more broadly, on the economics of technology. I am an Assistant Professor of Information Systems at the Gabelli School of Business, Fordham University.

My recent work examines topics including the economic and policy implications of the "sharing economy,'' the limits of online reputation systems, and the management of changes in P2P markets. My work has appeared in venues such as Management Science, the San Francisco Federal Reserve Bank, the ACM conference on Economics and Computation (EC), and the ZEW Conference on the Economics of Information and Communication Technologies (ICT). I earned my Ph.D. degree in business administration from NYU Stern School of Business, and my undergraduate degree in computer science (summa cum laude) from the University of Patras.
