Biography
Dr. McCurdy is an Assistant Professor in the Department of Psychiatry at Yale School of Medicine. Her program of research is centered on facilitating addiction recovery through empowerment and social connection. She has been involved in the development and evaluation of scalable digital interventions for addiction, including her social support intervention designed to support individuals in early addiction recovery by increasing engagement with recovery community resources.
Dr. McCurdy earned her Ph.D. in neuroscience at Yale University in 2020, where she identified the neural mechanisms for unlearning memories in the fruit fly. She then completed two National Institute on Drug Abuse (NIDA) T32 postdoctoral research fellowships at Yale School of Medicine: the Division of Prevention and Community Research’s training program in substance use prevention and the Neuroimaging Sciences Training Program. She joined the Department of Psychiatry at Yale School of Medicine as an Assistant Professor in January 2025.
