Chelsea Vadnie

Assistant Professor of Psychology and Neuroscience


  • B.A., Kenyon College
  • Ph.D., Mayo Clinic


Chelsea Vadnie joined the faculty at Ohio Wesleyan University in the fall of 2020. She received her undergraduate degree in Neuroscience at Kenyon College and her Ph.D. in Neurobiology of Disease at the Mayo Clinic (Rochester, MN) in the lab of Doo-Sup Choi. Her dissertation focused on using mouse models to understand the role of neurotensin signaling in mania-like behavior. Dr. Vadnie then completed a postdoctoral fellowship in Colleen McClung’s lab within the T32 Translational Research Training in Sleep Medicine Program at the University of Pittsburgh to gain expertise in sleep and circadian science.

Chelsea Vadnie is interested in using mouse models to study the role of circadian rhythm disruptions in behaviors relevant to anxiety, mood and alcohol use disorders. She uses optogenetics and environmental manipulations to understand whether circadian rhythm disruption alters behavioral phenotypes and neurobiology in mouse models. Her current project is centered on determining the role of the central pacemaker in the brain, the suprachiasmatic nucleus, in the regulation of mood and anxiety-like behavior. She also studies the behavioral and neurobiological effects of circadian disruption during adolescence.
