Wang, Lai-Sheng - Brown University - Department of Chemistry

个人简介

Lai-Sheng Wang is an experimental physical chemist interested in the study of nanoclusters and solution-phase chemistry in the gas phase. He received his B.S. degree in Chemistry from Wuhan University in 1982 and his Ph.D. in Chemistry from the University of California at Berkeley in 1990. After a postdoctoral stay at Rice University, he took a joint position between Washington State University and Pacific Northwest National Laboratory in 1993, then accepted an appointment at Brown in 2009. Dr. Wang's research focuses on the investigation of the fundamental behaviors of nanoclusters using photoelectron spectroscopy and computational techniques. Research in his group has led to the discovery of golden buckyballs and the smallest golden pyramid, as well as aromatic clusters and planar boron clusters. Dr. Wang's group has also pioneered spectroscopic studies in the gas-phase of free multiply-charged anions and complex solution-phase anions, such as metal complexes, redox species, and biologically-relevant molecules.
