Chemical Dynamics and Molecular Spectroscopy

Our research is concerned with the application of laser-based techniques in chemistry and materials science. We study the mechanisms of chemical and photochemical reactions, the spectroscopy and structure of reactive intermediates, atmospheric chemistry, analytical applications of laser spectroscopy, optical properties of aerosol particles, and laser ablation for thin-film deposition. Our work includes processes that occur in the gas phase, in liquids and at the surfaces of materials.
