Welcome to My Website! I am a Professor of Economics at Boston College. My research agenda focuses on the theory and practice of market design, with an emphasis on its applications in matching markets. I am best known for my contributions to the formulation, analysis, and practical design of kidney exchange, school choice and US Army’s branching process. My current research interests include design and analysis of transplant organ allocation policies, affirmative action schemes, pandemic medical resource allocation, immigration lottery allocation, as well as practical applications of matching with contracts. In my website you can find detailed information on my research program and its policy impact, slides for several recent presentations as well as for my mini-course on matching, and some other teaching material.
