The general focus of our research is the study of anatomical, physiological, and pharmacological mechanisms underlying pain sensation. Primary research interests include neural encoding of cutaneous and muscle pain. We are interested particularly in the neural mechanisms that account for hyperalgesia (enhanced sensitivity to pain) following tissue injury or disease, and the modulation of excitability of sensory neurons involved in pain transmission. Psychophysical, behavioral, and electrophysiological techniques are used in parallel studies using animals and humans.
