Professor
Sayamwong Hammack is a Professor in the Department of Psychological Science at the University of Vermont, serving as Director of the Neuroscience Graduate Program. His research focuses on neurobiological mechanisms underlying stress, emotion, and resilience, with emphasis on serotonin, PACAP, and CRH neuropeptides. Education: B.S. (Florida State University, 1995), M.A. (University of Colorado, 1998), Ph.D. (University of Colorado, 2001). Research interests include: Neurobiology of fear/anxiety circuits PACAP/CRH signaling in stress responses Role of exercise in mental health Serotonin neurotransmission Neurochemical mechanisms of stress resilience Publications emphasize PACAP's role in PTSD, trauma, and brain circuitry. Notable work explores PACAP's interaction with cortisol, fear extinction, and neuroimaging correlates of anxiety disorders. Lab affiliations include the Neuroscience Graduate Program. No awards explicitly listed, though research outputs indicate impactful contributions to stress neuroscience.
