Qinyi Chen

Ph.D. candidate in Operations Research at MIT
Email: qinyic@mit.edu

I am a fourth-year PhD student in the Operations Research Center (ORC) at MIT, where I am advised by Prof. Negin Golrezaei. Prior to MIT, I received my B.S. in Applied Mathematics with a specialization in computing from UCLA in 2020. In summer of 2023, I interned at eBay as an applied researcher intern.

 

My research centers around designing online learning and optimization algorithms for online platforms and marketplaces, with applications in online recommendation, assortment optimization, and ad bidding/pricing. Fascinated by the multi-sided dynamics between the platform and its various participants, I hope to design algorithmic approaches that help foster a more fair and efficient online ecosystem.
