My name is Peng Shi and I'm a 5th year PhD student at MIT Operations Research Center. I am interested in developing mathematical models and techniques that can significantly benefit society.
My current focus is prediction and optimization in matching markets, which include systems that match students to schools, applicants to subsidized housing, workers to jobs, and organ donors to recipients. Characteristics of these systems include heterogeneous supply and demand, potential strategic behavior of agents, and inability of obtaining the desired allocation by only setting prices. Much of my PhD work is motivated by school choice in Boston, for which I proposed an assignment plans that was adopted in March 2013 (for news coverage, see Vaznis (2012), Seelye (2013a), and Seelye (2013b)). I am currently working on developing theories and methodologies to assist future school choice reforms, and on applying optimization to other matching markets.
