About Me

I am an assistant professor of Operations Management at the University of Chicago Booth School of Business. My research interests are in extending the computational and mathematical boundaries of methods for solving the large-scale optimization problems that arise in data science, machine learning, and operations research. In particular, I am interested in (i) theory of convex and non-convex optimization motivated by statistical/machine learning problems; (ii) data-driven decision making with applications in advertisement allocation and machine scheduling; (iii) huge-scaling linear programming solving in the distributed setting (with applications at Google).

Before joining Booth, I was a visiting researcher at Google Research large-scale optimization team, where I primarily worked on designing and implementing a huge-scale linear programming solver. I obtained my Ph.D degree dual in Operations Research and Applied Mathematics at MIT in 2019, working with Robert M. Freund. Prior to MIT, I obtained my B.S. in Mathematics at Shanghai Jiao Tong University in 2014. My undergraduate advisor was David Cai from Courant Institute of Mathematical Science.
