I was born in Jingdezhen, China and graduated from Tsinghua University in Beijing, China. I got my Ph.D. in Mathematics at The Pennsylvania State University, working with Professor Yakov Pesin. I was a postdoc at University of Maryland and a Fields-Ontario postdoc at University of Toronto.

My main research interest is dynamical systems, which is a vibrant and diverse field that evolves around certain central ideas. Currently, I am interested in the following list of topics, all connected to the central idea of variational methods in Hamiltonian systems:
- Arnold diffusion (instability in Hamiltonian systems);
- Weak KAM theory and viscosity solutions of Hamilton-Jacobi equations;
- Normal form and averaging theory.
Here is a list of my publications and preprints.
I am currently teaching MAT1835 (graduate, Dynamical Systems).
I taught M232 (Multivariable Calculus) at UTM. I taught College Algebra, Calculus I, III, Differential Equations and Linear Algebra at Penn State University. In Maryland, I taught Math 140, 140H (calculus I), 141H (Calulus II), 241H (Calculus III), 412 (Advanced Calculus with applications) and STAT 100 (Elementary Statistics and Probability.
