About me

B.S. from Tsinghua, Ph.D. from PennState, and postdocs at UMD and Fields. My Ph.D. advisor was Yakov Pesin. I am proud of my hometown.


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:

I also work in smooth dynamics and thermodynamic formalism.
