Nathan Levitt, FNP-BC, MSN, RN, BSN, MA | Yale School of Nursing

I am the Director and co-founder of the Yale Pediatric Gender Program (YPGP), an interdisciplinary team that provides services for transgender and gender expansive (TGE) youth and families in Connecticut. The team includes professionals in the fields of psychology, endocrinology, psychiatry, gynecology, reproductive medicine, medical ethics and law. Our mission is to provide comprehensive, interdisciplinary, family-centered care for children, adolescents and young adults questioning their assigned gender and/or seeking gender-affirming consultation and care in a compassionate, respectful and supportive environment. This program is regionally well-regarded, serving clients from all 8 counties in the state, as well as 4 states outside of Connecticut. My contribution to the educational mission of Yale’s School of Medicine focuses on teaching trainees in clinical and research training programs about (a) trauma-informed care, (b) psychosexual development, and (c) gender development. Teaching occurs through the delivery of clinical services, mentoring of clinical and research trainees, clinical supervision, and lectures offered in graduate courses and topical seminars coordinated by other faculty members. I have been lucky to mentor and supervise many students in the departments of Psychiatry, the Child Study Center, the School of Public Health and the Divinity School during my tenure at Yale.

John Pachankis (he/him) is the Susan Dwight Bliss Professor of Public Health and directs Yale’s LGBTQ Mental Health Initiative, which serves as a home for scholarship devoted to understanding and improving the mental health of LGBTQ populations in the US and around the world.  His NIH-funded research program examines the efficacy of LGBTQ-affirmative mental health interventions delivered via novel technologies, in diverse settings, and across the spectrum of the LGBTQ community.  These treatments have shown often-times strong and sustained reductions in depression, anxiety, suicidality, substance use, and HIV risk across several randomized controlled trials.  He has published 150+ scientific papers on LGBTQ mental health and stigma and co-edited the Handbook of Evidence-Based Mental Health Practice with Sexual and Gender Minorities published by Oxford University Press. You can learn more about his research at https://medicine.yale.edu/lgbtqmentalhealth/

Chris Pittenger earned his MD and Ph.D. degrees from Columbia University, where his graduate work was done with Nobel Prize recipient Eric Kandel. He returned to Yale University, his undergraduate alma mater, for residency and research training in psychiatry in 2003. He joined the faculty as an Assistant Professor in 2007 and is now Elizabeth Mears and House Jameson Professor of Psychiatry, Professor of Psychology and in the Child Study Center, and Deputy Chair for Translational Research in the Department of Psychiatry .Chris has always been fascinated by the question of how the brain, a complex but ultimately a physical structure, creates thought, feeling, consciousness, and other aspects of the mind.  As a psychiatrist he is additionally focused on how these processes go wrong - how brain dysregulation leads to dysregulated cognition, emotion, and behavior and to mental suffering, and how advancing our understanding of these relationships can guide us to new strategies to alleviate that suffering.  Much of his work has focused on obsessive-compulsive disorder and Tourette syndrome and on the cortico-basal ganglia circuitry that is implicated in their pathophysiology.  More recently he has co-founded the Yale Program for Psychedelic Science, focused on understanding how molecules like psilocybin and LSD can teach us about brain and behavior and may lead to new treatments for a range of neuropsychiatric pathology.  He is also one of the founding Directors of the Yale Center for Brain and Mind Health, which seeks to bridge disciplines and levels of analysis to bring new therapeutics to individuals suffering from disorders of the mind and brain.Dr. Pittenger's research and clinical work have been acknowledged by a number of prestigious awards, including grant funding from the National Institute of Mental Health, the National Institute of Neurological Disease and Stroke, NARSAD, the Tourette Syndrome of America, the Doris Duke Charitable Trust, and other organizations.  He has won a number of awards, including from the National Institute of Mental Health, the Society for Neuroscience, the American College of Neuropsychopharmacology, the American Psychiatric Association, and the American College of Psychiatrists. He is a member of the Scientific Advisory Board of the International OCD Foundation and Chair of both their Grant Review Committee and their Annual Research Symposium Planning Committee.  He is a Fellow of the American College of Neuropsychopharmacology, the American Psychiatric Association, and the American Neurological Association.
