About Me

Hi! I'm a second-year Ph.D. student in the department of Operations Research and Engineering Management at Southern Methodist University, where I am fortunate to be advised by Dr. Harsha Gangammanavar. Before starting my Ph.D. studies, I earned an M.S. in Computational Mathematics from Xiamen University and a B.S. in Mathematics and Applied Mathematics from Hangzhou Dianzi University.

I am working on stochastic programming and large-scale optimization, in particular, multistage stochastic programming, sampling-based algorithm design, and nonsmooth optimization.

News

• July 2025: Our recent work, ``Comparative Study of Sampling-based Multistage Stochastic Linear Programming Algorithms", has been accepted for a poster presentation at ICCOPT 2025. (poster)
