個人經歷
Xudong Li is a tenure-track associate professor at theSchool of Data Science,Fudan Universityand theShanghai Center for Mathematical Sciences. He received his Ph.D. degree in Optimization fromNational University of Singaporein 2015 under the supervision of ProfessorsDefeng SunandKim-Chuan Toh. From 2015 to 2017, he was a research fellow in the Department of Mathematics at National University of Singapore. Prior to joining Fudan University in autumn 2018, he was a postdoctoral research associate in the Department of Operations Research and Financial Engineering atPrinceton Universitysupervised by ProfessorMengdi Wang. He obtained his Bachelor’s degree in Mathematics fromUniversity of Science and Technology of China.
He received the Young Researcher Prize in Continuous Optimization of the Mathematical Optimization Society in 2019 (awarded once every three years). Heis currently serving as an associate editor for Mathematical Programming Computation.
