Hi! I am a third-year Ph.D. student in the College of Computing and Data Science (CCDS) at Nanyang Technological University (NTU), supervised by Prof. Jie Zhang and Prof. Zhiguang Cao. I am currently conducting research at MIT’s Laboratory for Information and Decision Systems (LIDS), mentored by Prof. Cathy Wu. Previously, I received my M.Eng. degree from Sun Yat-Sen University (SYSU) in 2023, advised by Prof. Jiahai Wang, and received my B.Sc. degree from SYSU in 2020.

Research

My research interests focus on the intersection of Machine Learning (ML) and Optimization, striving to develop automated ML solutions to address complex optimization problems and decision-making challenges. Recently, I have been working on advancing neural combinatorial optimization solvers to address practical challenges, especially for vehicle routing problems.
