Bio. I am a postdoctoral scholar in the Division of Biology and Biological Engineering at California Institute of Technology, advised by Prof. Matt Thomson. Before that, I received the Ph.D. degree from Texas A&M University, advised by Prof. Yang Shen and co-advised by Prof. Zhangyang (Atlas) Wang, and the B.Eng. degree from Xi’an Jiaotong University. Please refer to my CV for more information.

My research focuses on machine learning on non-Euclidean data (e.g. graphs or point clouds) and in dynamical systems, with fundamental understanding in theory and applications to real-world problems in life sciences (in particular modeling of molecular and cellular systems). Please refer to my Google Scholar for a complete list of the established works.
