Yuxin (Louis) Liu

I am a third-year PhD student in Operations Research at the Department of Industrial Engineering, University of Pittsburgh. I am fortunate to be advised by Prof. Amin Rahimian. Prior to Pitt, I received my B.S. in Economics from Jilin University (June 2020) and my M.E. in System Engineering from Tianjin University (June 2023).
My research passion lies at the intersection of social learning, game theory, privacy-preserving mechanisms, and information diffusion. Here is my CV. Feel free to contact me via Email (YUL435@pitt.edu).

Thrilled to chair the Privacy-Preserving session at the INFORMS Annual Meeting 2025, and to share my work "Privacy-Aware Sequential Learning". Oct. 26, 2025
