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. My research centers on designing ML and optimization algorithms tailored for operations of digital marketplaces, including online advertising, recommender systems, revenue and inventory management. My research interests span multi-armed bandits and RL, game and auction theory, data-driven optimization and AI/ML fairness.

 

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 Search & Monetization Team as an applied researcher intern.
