Xinyou received his B.S. degree in Chemistry from Beijing University of Chemical Technology, China in 2011 and Ph.D. Degree in Chemistry from Texas Tech University in 2018. During his Ph.D. study, he worked on chemical dynamics simulation under the supervision of Dr. Bill Hase. His research focused on gas phase ion-molecular reaction and interactions including 1) non-RRKM dynamics using classical and quasi-classical trajectory simulation, 2) anharmonic spectroscopy with semiclassical theory, 3) anharmonic intermolecular vibrational density of states using Monte Carlo simulation, 4) rotational and vibrational effects vibrational mode coupling, 5) development a particle swarm optimization method for fast fitting analytic PES.
