Dong Chen - PSU Mathematics PhD Student

Dong Chen

Personal Information

I am a sixth-year graduate student in Department of Mathematics. My advisor is Dmitri Burago. My research is focused on differential geometry and dynamical systems. It includes problems from KAM theory, inverse problems, hyperbolicity, Finsler geometry, Aubry-Mather theory etc. I am particularly interested in the interaction between KAM-nondegenrate nearly integrable systems and geodesic flows.
