Joshua Williams is an Associate Professor and Chair of the Physics Department at the University of Nevada, Reno. His research focuses on atomic and molecular physics, with an emphasis on photoelectron dynamics, interatomic Coulombic decay, and core ionization processes. He holds a Ph.D. in Physics from Auburn University (2012), following an M.S. (2011) and B.S. (2006) in Physics from Auburn University and the University of South Alabama, respectively. Prior to his faculty role, he was a Postdoctoral Research Fellow at Goethe-Universität Frankfurt am Main (2012–2015).
Dr. Williams' work utilizes advanced experimental techniques such as COLTRIMS (Cold Target Recoil Ion Momentum Spectroscopy) to study ultrafast molecular dynamics. His research spans topics including molecular frame photoelectron angular distributions, electron correlation effects in photoionization, and the interplay between electronic and nuclear motion in dissociating systems. His recent studies investigate core hole localization in molecules like methane and dichloroethylene, as well as chiral asymmetry in formic acid and trifluoromethyloxirane.
His publications highlight contributions to understanding interatomic Coulombic decay in molecular dimers, dissociation dynamics of water dications, and electron localization effects in hydrogen and deuterium systems. He collaborates internationally on projects involving X-ray free-electron lasers and ultrafast electron diffraction imaging.
Awards and grants are not explicitly listed in the provided text. He advises no named students, though his research involves a collaborative team. His experimental work often centers on imaging molecular structure and dynamics through photoelectron spectroscopy, with applications to fundamental physics and chemical reaction mechanisms.
