Glenn S. Edwards
Professor of Physics
Glenn Edwards investigates biological systems using a range of experimental techniques and theoretical methods from physics. His interests include Investigations of energy transduction where laser energy transforms into vibrational energy of biological molecules which then transforms into heat and pressure pulses that selectively drive tissue-scale dynamics. This line of research has led to human surgical applications of Free-Electron Lasers and spin-off laser technology. Another interest includes investigations of how biology harnesses physical mechanisms in biomechanical processes. This line of research investigates tissue dynamics and pattern formation during early development in Drosophila embryos.
