Biography
Terence Ching (he/him) is a licensed clinical psychologist and instructor in the Department of Psychiatry. Terence leads psilocybin clinical trials for OCD and other disorders as part of the Yale OCD Research Clinic, Emerging and Novel Applications for Consciousness-Altering Therapeutics (ENACT) Research Collaborative, and the Yale Program for Psychedelic Science. In these spaces, Dr. Ching also assumes the role of Director of Psychedelic Training, pioneering the training and supervision of numerous facilitators who work with study participants in psychedelic dosing sessions.
Terence received his PhD in clinical psychology from the University of Connecticut. Prior to moving to the United States, Terence received his Bachelor’s and Master’s degrees in psychology from the National University of Singapore.
He has interests and expertise in: (1) fear-/trauma-based disorders (OCD, anxiety disorders, PTSD); (2) exposure-based, integrative cognitive-behavior therapies (CBT); (3) culturally attuned care; and (4) therapeutic applications of psychedelics.
Terence has completed clinical training in a variety of settings, including the University of Connecticut, the Institute of Living, as well as Dartmouth-Hitchcock Medical Center. Terence approaches psychotherapy from an evidence-based and culturally attuned perspective, and specializes in exposure-based CBT for fear-/trauma-based disorders.
In the psychedelic therapy space, Dr. Ching is an extensively published global leader in culturally attuned, queer- and trans-affirming, and ethically rigorous care of individuals experiencing altered states of consciousness. Dr. Ching has served as a study therapist in pivotal clinical trials of MDMA-assisted therapy (MDMA-AT) for PTSD, and has substantial experience providing ketamine-assisted psychotherapy (KAP) for individuals with varied mental health problems.
