Biography
Nii Addy is the Albert E. Kent Associate Professor of Psychiatry and Associate Professor of Cellular and Molecular Physiology and the inaugural Director of Scientist Diversity and Inclusion at Yale School of Medicine. He is also Director of the Faculty Mentoring Program for the Minority Organization for Retention and Expansion (MORE) and co-chair of the Career Development Subcommittee of the Anti-Racism Task Force in the Yale Department of Psychiatry. He contributes to graduate student and postdoctoral training and to diversity, equity, and inclusion initiatives through his efforts on campus and in scientific societies.
He received his B.S. in Biology from Duke University and his Ph.D. in Neuroscience from Yale University. Dr. Addy directs a federally funded research program investigating cholinergic, dopaminergic and L-type calcium channel mechanisms mediating substance use and mood disorders. Dr. Addy’s team also studies the ability of tobacco product flavor additives to alter nicotine use behavior and addiction. He serves on the journal editorial board of Neuropsychopharmacology, Biological Psychiatry, and Neuropharmacology, and he previously served as a grant reviewer for the Neurobiology of Motivated Behavior (NMB) Study Section of the National Institutes of Health's Center for Scientific Review (CSR).
In addition to his campus work, Dr. Addy hosts the Addy Hour podcast, discussing topics at the intersection of neuroscience, mental health, faith, culture and social justice. Episodes include dynamic conversations based on the lived experience and professional expertise of his guests - which include community leaders, clinicians and mental health experts, scientists, professional athletes and entertainers, faith leaders, and mental health advocates. As the creator and host of town hall community events, Dr. Addy has also built unique partnerships to encourage and equip audiences to embrace the use of holistic, integrated tools to address mental health challenges. He has collaborated with Lecrae (Grammy Award-winning artist and NY Times Best Seller), Doug Middleton (Jacksonville Jaguars/ Dream the Impossible Initiative), Allan Houston (former NBA All-Star, NY Knicks/ FISLL Project), the National Alliance on Mental Illness (NAMI), the Veritas Forum, the Anxiety and Depression Association of America (ADAA), the Association for Behavioral and Cognitive Therapies (ABCT), the Yale University Chaplain's Office, Yale Well, the Salvation Army, Every Nation Church NYC, the American Bible Society and others. His research and community work have been featured by National Public Radio (NPR), Newsday, the National Football League Players Association (NFLPA), The Source Magazine, Chuck Norris, BoldTV, Legitimate Matters, and Relevant Magazine. He has presented scientific lectures at universities throughout the United States and Europe, and he serves on the Board of Trustees for The Carver Project, aimed at empowering and connecting individuals across university, church and society.
