Qinyi Chen

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

I am a final-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.

 

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, fair and responsible AI, data-driven optimization and game and auction theory.
