Marya Gwadz is a licensed clinical psychologist and Associate Dean for Research and Professor at the New York University Silver School of Social Work. Dr. Gwadz is an Associate Director of the Transdisciplinary Research Methods Core of the Center for Drug Use and HIV Research, in which she has played a leadership role since 2005. The main focus of Dr. Gwadz’s research is the development and evaluation of potent, innovative, multi-level culturally salient interventions to address racial/ethnic and socio-economic disparities in HIV. Her work with populations in high-risk contexts spans over two decades and has focused on sub-groups such as runaway/homeless youth, young men who have sex with men (YMSM), heterosexuals at high risk for HIV, substance-using populations, low socioeconomic status populations, and persons of color living with HIV/AIDS.
