Research in theoretical and experimental physical chemistry includes ultrafast study of reaction dynamics, computational chemistry, molecular interaction in liquids, photoacoustics, and applications of chemical physics to medical imaging. The heart of Brown’s experimental research in physical chemistry is the use of multiple ultrashort-pulsed laser systems, allowing ultrafast time-resolved methods for electron diffraction, spectroscopy, and x-ray absorption.
