Sun was born in Dingyuan County, Anhui Province, in July 1991 and graduated from Yunnan Normal University in 2012. From 2013 to 2018 , I studied Hamiltonian dynamical systems at Fudan University under the supervision of Professor Yuan Xiaoping and received my PhD in July 2018 .  I joined Yangzhou University as a full-time faculty member in November 2018 .  At present, I am mainly engaged in the study of near-integrable Hamiltonian systems. One of the main research directions is the KAM theory, which goes back to the old problem of the stability of planetary motion in the Solar System. My current work includes stability estimates for linear PDEs in compact spaces, stability and diffusion of Schrödinger equations on lattice systems.
