Biography
Dr. Robert H. LaMotte is a Professor of Anesthesiology and of Neuroscience at the Yale School of Medicine. Before joining Yale, Dr. LaMotte was a PHS Postdoctoral Fellow of Physiology and an Assistant Professor of Psychology and Physiology at The Johns Hopkins School of Medicine. He received his MS and PhD from Kansas State University and became a NASA Fellow of Psychology there in 1964. Dr. LaMotte received the Jacob K. Javits Neuroscience Award in 1984 and again in 1991. He was the Associate Editor of The Journal of Neuroscience from 1981 to 1985 and has been on the Editorial Board of a range of medical journals, most recently, Pain Forum and The Journal of Pain. Dr. LaMotte now runs his own laboratory at the Yale School of Medicine using the methods of single-cell electrophysiology and sensory psychophysics to study the peripheral neural mechanisms of pain and itch in humans and animals.
