She received her PhD in clinical psychology from the Illinois Institute of Technology in Chicago, IL, and was a clinical psychology resident at the Edward Hines Jr VA. Dr. Guy completed an NIMH-funded T32 fellowship in Biobehavioral HIV research at Brown University in the Department of Psychiatry and Human Behavior, while cross-training with the Alcohol Research Center on HIV (ARCH) and Center for Alcohol and Addiction Studies (CAAS) in the School of Public Health. Dr. Guy's work focuses on community-based participatory research with queer and trans communities to develop and implement evidence-based behavioral health interventions. Their work aims to heal negative psychological sequelae resulting from stigma, support addiction recovery, increase access to gender affirmative care, and reduce HIV health inequities. Dr. Guy is the PI of a NIDA-funded K99/R00 to adapt and test an acceptance and commitment therapy (ACT)-based, gender-affirming stigma intervention that targets substance misuse and HIV risk among trans women. Her work spans across the Alcohol Research Center on HIV (ARCH), the Center for Alcohol and Addiction Studies (CAAS), and the Mindfulness Center at Brown.
