Glenn S. Edwards

Professor Emeritus of Physics
Physics

French Family Science Center, 2314, Durham, NC 27708

Overview


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.

Recent Publications


Mathematical models of dorsal closure.

Journal Article Progress in biophysics and molecular biology · September 2018 Dorsal closure is a model cell sheet movement that occurs midway through Drosophila embryogenesis. A dorsal hole, filled with amnioserosa, closes through the dorsalward elongation of lateral epidermal cell sheets. Closure requires contributions from 5 dist ... Full text Cite

Unified biophysical mechanism for cell-shape oscillations and cell ingression.

Journal Article Physical review. E · June 2018 We describe a mechanochemical and percolation cascade that augments myosin's regulatory network to tune cytoskeletal forces. Actomyosin forces collectively generate cytoskeletal forces during cell oscillations and ingression, which we quantify by elastic p ... Full text Cite

Cell Sheet Morphogenesis: Dorsal Closure in Drosophila melanogaster as a Model System.

Journal Article Annual review of cell and developmental biology · October 2017 Dorsal closure is a key process during Drosophila morphogenesis that models cell sheet movements in chordates, including neural tube closure, palate formation, and wound healing. Closure occurs midway through embryogenesis and entails circumferential elong ... Full text Cite
