Yuxin Liu
I am a third-year PhD student in Operations Research in the Department of
Industrial Engineering at the University of Pittsburgh, where I am fortunate to
be advised by Prof. M. Amin Rahimian. Prior to Pitt, I received my B.S. in
Economics from Jilin University in June 2020 and my M.E. in Systems
Engineering from Tianjin University in June 2023.
My research interests lie at the intersection of social learning, game theory,
privacy-preserving mechanisms, and information diffusion. Please feel free to
contact me at YUL435@pitt.edu.
