Christopher Nicholas, PhD (he/him/his) is DFMCH faculty whose research focuses on the clinical efficacy and therapeutic mechanisms of psychedelic (psilocybin, MDMA, 5-MeO-DMT) and other psychoactive compounds (ketamine) for addiction, PTSD, chronic pain, and depression. He is currently investigating psilocybin-assisted therapy for methamphetamine and opioid use disorders, ketamine-assisted therapy for adolescent PTSD, and the therapeutic role of memory salience and neuroplasticity post-psilocybin.
He earned his PhD in clinical psychology and neuroscience at the University of Tennessee and completed his post-doctoral fellowship in aging and multi-modal neuroimaging at the University of Wisconsin School of Medicine and Public Health and William S. Middelton Memorial Veterans Hospital.

Research Interests
Nicholas’s research interests include the clinical efficacy and therapeutic mechanisms of psychedelic and other psychoactive compounds for addiction, trauma, chronic pain, and depression. He also integrates fMRI as a biomarker in his clinical trials and is interested in the application of predictive processing as a transdiagnostic mechanistic framework.
