Acute or chronic pain that requires medical attention affects an estimated 45% of Americans annually. Despite its importance and often compelling insistence, mechanisms of pain and of pain control are incompletely understood. A principal focus of the laboratory is investigation of the mechanisms of enhanced sensitivity to pain, termed hypersensitivity or hyperalgesia (a plastic change in the nervous system), that develops following tissue injury. A complementary research focus is study of the organization and operation of endogenous systems of pain control and their contribution to chronic pain states.


Experimental approaches include: single sensory nerve fiber recording, patch clamp recording from identified nerve cell bodies in dorsal root ganglion neurons, and procedures for quantification or localization of peptides, G protein-coupled receptors, immediate early genes and ion channels that play an important role in pain.
