I am a Ph.D. candidate in Business Economics at Harvard University. In July 2026, I will join New York University’s Stern School of Business as an Assistant Professor of Economics, following a one-year postdoc at Princeton University’s Economics Department.

My research focuses on industrial organization. You can download my CV here. Feel free to reach me at jgortmaker@g.harvard.edu. For inquiries about software, you can contact me directly or use the issue tracker.
