Biography:Hammack is an assistant professor of psychology. His research is focused on understanding the neurobiological mechanisms of emotion and emotional learning, with an emphasis on fear and anxiety behaviors. He uses a variety of techniques to investigate these mechanisms, which include assessing conditioned and unconditioned fear and anxiety, pharmacological manipulations, neuroanatomical techniques, and intracellular electrophysiological techniques. He is particularly interested in the involvement of the neurotransmitter serotonin in emotional behavior, and the mechanisms of therapeutic action of drugs that modulate serotonergic systems, such as selective serotonin reuptake inhibitors (SSRIs).
