I am an Assistant Professor in the Department of Economics at Kyung Hee University. My research applies industrial organization and applied microeconomics to study how digital platforms and artificial intelligence reshape participation, pricing, and welfare in labor and consumer markets. I am also interested in agentic commerce—how AI agents acting on behalf of consumers shape search, choice, and market outcomes. Previously, I was an Assistant Professor of Economics at the Haslam College of Business, University of Tennessee. I obtained my Ph.D. in Economics from the University of Virginia, where I was advised by Prof. Simon Anderson and Prof. Gaurab Aryal.
