Xiang Sun received his B.S. in chemical physics from University of Science and Technology of China in 2008 and his Ph.D. in chemistry from Brown University in 2014. He did his postdoctoral research at the University of Michigan from 2014 to 2017. He is now an assistant professor of chemistry at NYU Shanghai.
Professor Sun is interested in photo-induced chemical dynamics in complex molecular systems such as liquid solutions, surfaces, biological systems, and nanomaterials. A fundamental goal is to obtain a molecular-level understanding of how electronic and vibrational excitation influence the mechanisms, outcomes, and spectroscopic signatures of chemical dynamics in the condensed phase. Since electronic and vibrational relaxation usually has a quantum nature, it is highly desirable to have methods that accurately describe the relevant quantum dynamical effects, while still being computationally feasible for large-scale systems like classical methods do. The Sun group is focused on developing mixed quantum-classical and semiclassical methods for dynamics following molecular excitation with the help of statistical mechanics, electronic structure theories, and the path integral formalism. Having an insight into the many-body dynamics helps us learn the molecular lessons of ultrafast nonlinear spectroscopies and gain a deeper understanding of charge and energy transfer dynamics in light-harvesting molecules and organic photovoltaic materials.
