Andrew J Alexander

Dr Andrew J Alexander is a Reader in Chemical Physics at The University of Edinburgh, Department of Chemistry. His research focuses on the interaction between light and matter, particularly in the areas of nucleation, nanobubbles, crystallization, and crystalloluminescence. His group uses polarized laser light to stimulate chemical processes and study their dynamics. Notable work includes laser-induced nucleation of carbon dioxide bubbles and the first measurement of crystalloluminescence from sodium chloride crystals. His research has implications for understanding and controlling crystallization processes in industrial applications.

Andrew J. Alexander's research focuses on laser-induced nucleation, chemical physics, reaction dynamics, and crystallization. His work explores the mechanisms of crystal nucleation under non-photochemical conditions, particularly in potassium halides and supercooled glacial acetic acid. He investigates the spatial control of nucleation in agarose gel and the effects of activation schemes on porous and thermal properties of activated carbons. Alexander also examines photofragment helicity, stereodynamics, and the electronic properties of carbon nanotubes. His studies contribute to understanding reaction dynamics through state-resolved angular momentum distributions and the role of nonadiabatic processes in photodissociation.
