Research Abstract:

Stress can dramatically alter motivated behavior, leading to maladaptive decision-making, depression, anxiety, and addiction. The stress response is controlled by G-protein coupled (GPCR) neuromodulator receptors in the central and peripheral nervous system. A vast number of pharmaceutical agents directly target GPCRs. We are interested in discovering how GPCR receptor systems function in the context of stress-induced affective behaviors including anxiety, depression, pain, and addiction. We adopt a multidisciplinary, cutting-edge approaches including optogenetics and in vivo imaging to study the pharmacological, biochemical, physiological, and neurobiological basis of stress and affective behaviors.
