Wei Xiong is an experimental physical chemist in the Department of Chemistry and Biochemistry at the University of California, San Diego. Dr. Xiong received his B.S. in Chemistry from Peking University and a Ph.D. in Physical Chemistry from the University of Wisconsin, Madison, where he worked with Prof. Martin Zanni, focusing on developing ultrafast nonlinear infrared spectroscopy to measure molecular structures and dynamics at interfaces. He then joined the University of Colorado, Boulder and JILA as a postdoctoral researcher, working with Professors Margaret Murnane and Henry Kapteyn to develop photoelectron spectroscopy and high harmonic generation for studying electronic dynamics of nanoparticles. He started his independent career at the University of California, San Diego, in 2014. His research group investigates ultrafast molecular dynamics of materials and biological systems by follow them in space, time, and energy domains, using nonlinear optical spectroscopy. In particular, he focuses on understanding ultrafast vibrational dynamics of molecular vibrational polaritons, hybrid quasiparticles formed when molecular excitations and photonic modes are strongly coupled. His research shed light on the mechanism of how polaritons can modify chemistry and the potential applications of polaritons in quantum technologies. His group also developed nonlinear optical imaging techniques to resolve the microscopic and mesoscopic structures of self-assembled materials. As an educator, he is interested in finding new ways to engage the next generation of scientists in physical chemistry research. He has received the NSF CAREER Award, DARPA Young Faculty Award, AFOSR Young Investigator Program Award, the Journal of Physical Chemistry Lectureship, and Sloan Research Fellowship. He has served as a guest editor for the Journal of Chemical Physics and is a member of the Editorial Advisory Board of the Journal of Physical Chemistry. He aims to create more opportunities for young physical chemists from all backgrounds.
