Xiang Sun is an Assistant Professor of Chemistry at NYU Shanghai. Prior to joining NYU Shanghai, he was a postdoctoral research fellow at the University of Michigan, Ann Arbor and a visiting scholar at the University of California, San Diego. He holds a Ph.D. in Chemistry from Brown University and a B.S. in Chemical Physics from the University of Science and Technology of China (USTC).
Professor Sun is interested in photoinduced chemical dynamics in complex molecular systems such as liquid solutions, surfaces, and functional 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 semiclassical and mixed quantum-classical methods for understanding dynamics following molecular excitation with the help of statistical mechanics, electronic structure theories, and Feynman’s 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.
