Chamsi Hssaine

Ph.D. Candidate

Cornell University

I am a final-year Ph.D. candidate in Operations Research at Cornell University, where I’m fortunate to be advised by Professor Siddhartha Banerjee. I obtained my B.S.E. in Operations Research and Financial Engineering from Princeton University, with a minor in Applied Mathematics.

My research lies at the intersection of operations research and economics, focusing on algorithm and incentive design for smart societal systems. More specifically, I am interested in developing tools for these people-centric systems, with an emphasis on incorporating more realistic models of behavior under incentives.

In the fall of 2019, I was a visiting graduate student at the Simons Institute program on Online and Matching-Based Market Design. In addition to my academic work, I worked as an applied science intern at Amazon on the Personalization and Long-Term Optimization team in the summer of 2020, as well as a research intern at RAND in the summer of 2018.
