Christopher En
I am a 3rd-year Ph.D. student at Columbia IEOR, where I am fortunate to be advised by Professor Yuri Faenza and Professor Eric Balkanski.
My research interests broadly involve market design, matching, and discrete optimization. In particular, I am interested in developing mathematically fair and provably efficient mechanisms for market settings that bridge the gap between classical models and practical applications. Some current research topics include:
Matching with nonlinear utilities and transfers
Nondistributive lattices and optimization over stable matchings
Dynamic matching and refugee resettlement
My work is funded in part by a Columbia University Presidential Fellowship, as well as a Cheung-Kong Innovation Doctoral Fellowship.
I obtained an A.B. in Mathematics from Harvard, where I was advised by Professor David Parkes.
