Stacey B. Armstrong, PhD is a senior researcher and psychologist at the Center for Psychedelic Drug Research and Education (CPDRE) at The Ohio State University College of Social Work. She earned her Ph.D. at Bowling Green State University after completing a clinical internship at the University of Michigan in Ann Arbor, MI. Her clinical fellowship at the Traumatic Stress Center in Akron, OH, emphasized the utilization of evidence-based treatments for posttraumatic stress disorder (PTSD) among veterans and civilians, including cognitive processing therapy (CPT) and prolonged exposure (PE). She also completed a research fellowship at The Ohio State University evaluating the safety and efficacy of psilocybin, a novel investigational psychedelic drug, in treating treatment-resistant PTSD among US military veterans. In addition to her work with PTSD, Dr. Armstrong is also collaborating on a clinical trial investigating the safety and efficacy of psilocybin in treating depression among lung cancer patients. She is also investigating the patterns of use and acute subjective effects of psychoactive substances in clinical and non-clinical settings, measuring the attitudes and beliefs about psychedelic-assisted therapies among mental health professionals, and helping to develop a global registry for opioid use disorder patients who have sought psychedelic therapy in international locations to obtain real-world evidence on the safety and effectiveness of ibogaine as an addiction treatment. She has a particular interest in the subjective effects of psychedelics and their impact on treatment outcomes, as well as how psychedelic-assisted therapies might benefit populations currently excluded from clinical trials.
