Clayton Olash
Affiliate, Psychiatry and Behavioral Sciences
BioClayton Olash, MD is a psychiatry resident at the Medical University of South Carolina and an affiliate researcher with Stanford University. His work bridges psychiatry, neuroscience, and contemplative traditions, with a focus on how altered states of consciousness can catalyze lasting psychological change.
Clayton's current research spans multiple projects, including studies on ibogaine and its impact on the default mode network, rapid-acting neuromodulation techniques such as SAINT TMS combined with meditation, and a novel high-dose electrotherapy device for home-based treatment of depression. His broader aim is to understand how psychedelics, brain stimulation, and meditative practices can modulate self-related processing and promote enduring well-being.
With backgrounds in philosophy, psychology, and medicine, Clayton's work emphasizes integration: uniting ancient contemplative wisdom with modern neuroscience and emerging technologies. His long-term goal is to develop translational models of care that transform transient altered states into sustainable therapeutic traits. -
Alisa Marie Olmsted
Clinical Assistant Professor (Affiliated), Psych/General Psychiatry and Psychology (Adult)
BioI am a board-certified psychiatrist specializing in interventional treatments for mood disorders, including transcranial magnetic stimulation (TMS), esketamine, and intravenous ketamine. I completed an Advanced MD Fellowship at the Sierra Pacific Mental Illness Research, Education, and Clinical Center (MIRECC), a Veterans Affairs (VA) Center of Excellence at VA Palo Alto, where my work focused on circuit-based approaches to precision psychiatry. I completed residency at Jefferson University Hospital, where I served as research chief and served on the ethics board, gaining broad clinical experience across inpatient, emergency, consultation-liaison, and addiction psychiatry. My research on Veterans has been published in Nature Mental Health and the Journal of Affective Disorders Reports, while my earlier clinical work was cited in The New York Times. I have provided continuous care to Veterans since medical school, including at the Hunter Holmes VA, where I earned honors, and at the Wilmington VA community-based outpatient clinic (CBOC). My commitment to serving Veterans is informed by a family legacy that includes multiple generations of combat Veterans, a perspective that continues to shape my clinical and research priorities within the VA system.
