DAVID L. ANDREWS leads research on fundamental molecular photonics and energy transport, optomechanical forces, and nonlinear optical phenomena. He has over 300 research papers and a dozen of books to his name—including the widely adopted textbook, Lasers in Chemistry. The current focus of his research group is on optical vortices, novel mechanisms for optical nanomanipulation and switching, and light harvesting in nanostructured molecular systems. The group enjoys strong international links, particularly with groups in Canada, Lithuania, New Zealand, and the United States. Andrews is a Fellow of the Royal Society of Chemistry, a Fellow of the Institute of Physics, and a Fellow of SPIE, the international society for optics and photonics.
