I am a professor at the Antai College of Economics and Management of Shanghai Jiao Tong University and the dean of the Institute for Intelligent Computing(SJTU-IIC). I obtained my PhD from the Department of Management Science and Engineering at Stanford University in 2009. My main research interests are in the theory, computation, and application of large-scale optimization problems. I publish papers in journals and conferences across multiple fields such as MS/OR/TCS/AI, including OR, MOR, MP, POM, FOCS, SODA, EC, ICML, NeurIPS, etc..I'm also a co-founder and chief scientist of Cardinal Operations(shanshu.ai) and has participated in numerous optimization projects with companies and organizations worldwide, such as Boeing, Google, Huawei, JD.com, SF Express, DiDi, State Grid Corporation of China/Southern Power Grid, and China Southern Airlines. Currently, I serve as the project leader for China's first open-source mathematical programming software LEAVES and the first commerial mathematical programming software COPT project.
