I am currently a postdoctoral researcher at University of California Santa Cruz and Tsinghua University. My research interests are focused on the collisional and dynamical evolution of small planetary bodies, rings, and moons. I developed a open-source SPH code for simulating hypervelocity impacts and tidal responses of planetary bodies. I am eager to exploring any unsolved exciting questions of our solar system using theoretical and numerical methods and open to collaborations.
