Biosketch

Dr. Wenzel is interested in the neurochemical systems underlying positive and negative reinforcement learning and how experiences throughout development (e.g. drug use or stress) shape reinforcement processes.

In 2005, Dr. Wenzel completed her B.S. in Psychology at Arizona State University. At ASU her interest in behavioral neuroscience developed while working as a research assistant in Dr. Janet Neisewander’s Laboratory  on a series of projects investigating the involvement of dopamine signaling in the amygdala in drug- and cue-induced reinstatement of cocaine seeking.

Dr. Wenzel received her PhD in Neuroscience and Behavior from the University of California Santa Barbara, where she worked in Dr. Aaron Ettenberg's laboratory. Her graduate work focused on the neurobiology underlying the opponent processes of cocaine. More specifically, she found that norepinephrine signaling in the extended amygdala is integral to the experience of the negative/anxiogenic, but not the positive/euphoric, effects of acute cocaine administration.

In the summer of 2013, Dr. Wenzel joined the laboratory of Dr. Joseph Cheer as a postdoctoral scholar. Her research here at UMB explores a number of topics, including; the role of dopamine and endocannabinoids in active avoidance, how corticostriatal and endocannabinoid signaling influences impulsive choice, and the effects of adolescent cannabinoid exposure on cocaine reward and reinforcement.

Research Interests

The neurobiology of motivated behaviors

  • What brain systems mediate approach and avoidance?
  • How do prior experiences (e.g. adolescent drug exposure, social isolation) shape reinforcement learning and underlying neural circuitry?
  • How are traits linked to motivation, like impulsivity, represented in the brain?
