I am an applied theorist whose research interest lies in the intersection between Industrial Organization, Microeconomic Theory, and Strategy. My research has often focused on the economics of innovation, competition policy, and market entry. Recently, I have been exploring how market competition affects the provision of health insurance and the health outcomes of individuals. I graduated from Northwestern University and previously served as an assistant professor at UBC's Sauder School of Business.
