Research Results:

• John William Hatfield and I have developed a theory of "matching in networks," isolating a technical frontier of classical matching theory. (2/26/10)
• John William Hatfield and I have thoroughly developed the theory of "many-to-many matching with contracts." (7/3/09) Read more on Market Design [Blog]. (10/10/09)
• Every large point set contains many collinear points or an empty pentagon. (4/3/09)
• Candy-passing games stabilize in polynomial time: Paul Kominers and I have shown that polynomial stabilization occurs whenever there are sufficiently many candies. (7/29/08)
• Hypercubic robots are arbitrarily reconfigurable: Zachary Abel and I have fully generalized a result of Dumitrescu and Pach concerning two-dimensional modular metamorphic systems. (2/27/08)
• The lazy mathematician wins: Justin G. Chen, Robert W. Sinnott, and I have shown why one should always catch the MIT-Harvard bus at Lobby 7. (1/20/08)
• Hinged dissections exist! (12/13/07)

Media Appearances:

• I received a sort of "guest post" on Al Roth's Market Design [Blog]. (12/24/08)
• Walk versus Wait: The Lazy Mathematician Wins was featured in the 2008 New York Times "Year in Ideas!" (12/13/08)
• I recently appeared in Amerikas andere Seite - Was Kalifornien besser macht, a German television documentary involving Google. (11/20/07)
