I joined Kang Feng's group in Computing Center, Chinese Academy of Sciences in 1987, right after I got the Bachelor of Mathematics from Fudan University. Successively, I got MS and PhD in CAS in the 1990s and became a staff member of Computing Center and Feng's research assistant in 1990. I joined this institute in 1997. My research interest includes Symplectic Methods for Hamiltonian Systems, Machine Learning and Dynamical Systems, Numerical Analysis of Fractional Differential Equations with Applications.
