Research
My research interests are Game Theory, Market Design, Industrial Organization, and Microeconomic Theory. I have published papers in top economics journals, including American Economic Review, AEJ: Microeconomics, Journal of Economic Theory, Journal of Mathematical Economics, and RAND Journal of Economics, as well as leading journals in other fields such as AAMAS, Artificial Intelligence, and Scientific Reports.
