|  Biography

Marya Gwadz is Associate Dean for Research, Professor, and Director of the Intervention Innovations Team Lab (IIT-Lab) at NYU Silver. She also serves as an Associate Director in the Transdisciplinary Research Methods Core in the NIDA-funded Center for Drug Use and HIV Research (CDUHR) at NYU School of Global Public Health.

The main focus of Dr. Gwadz’s research is the development and evaluation of potent, innovative, and culturally salient social/behavioral interventions to address racial/ethnic, socioeconomic, and gender inequity in health. Her work with vulnerable adolescent and adult populations spans three decades and focuses on populations such as persons with substance use problems, sexual and gender minorities, heterosexuals in high-risk contexts, populations with high rates of criminal justice involvement, runaway/homeless youth, and people of color living with HIV from low socioeconomic status backgrounds. Dr. Gwadz’s program of research has been continually funded by the NIH since 2000.

Dr. Gwadz is an expert on the multiphase optimization strategy (MOST), a framework for developing efficient and cost-effective interventions with no inactive, poorly performing, or counter-productive elements. She is currently Co-Principal Investigator on a NIDA-funded study using MOST to optimize an intervention for vulnerable populations living with HIV (R01DA040480) with Dr. Linda Collins, the original developer of MOST. Their study is the first application of the MOST framework in the field of HIV treatment and prevention. She is also an expert on adaptive trial designs, including sequential multiple assignment randomized trials (SMART).

Prior to joining NYU Silver, Dr. Gwadz was a Senior Research Scientist at NYU Rory Meyers College of Nursing, and Director of CUDHR’s Transdisciplinary Research Methods Core. She has played a leadership role in CDUHR since 2005.

A licensed clinical psychologist, Dr. Gwadz earned her PhD and MA in clinical psychology from NYU and her BA in psychology from the University of Rochester.

Featured Research Project

The Heart to Heart 2 Project

As noted above, Dr. Gwadz is Co-Principal Investigator on a $5.8 million National Institute of Drug Abuse-funded study (R01DA040480) using the multiphase optimization strategy framework (MOST) to optimize an intervention for vulnerable populations living with HIV. The five-year study aims to develop a highly efficacious, efficient, scalable, and cost-effective intervention to foster engagement along the HIV care continuum for Black and Latino PLWH who rarely attend HIV primary care appointments and are not taking HIV antiretroviral therapy.

Funded Projects

Using the multiphase optimization strategy (MOST) to optimize an intervention to increase COVID-19 testing for Black and Latino/Hispanic frontline essential workers

The National Institute on Minority Health and Health Disparities has awarded Dr. Marya Gwadz a two-year, $2.3 million grant to use the multiphase optimization strategy (MOST) framework to optimize an intervention to address the challenge of insufficient COVID-19 testing among Black and Latino/Hispanic (BLH) frontline essential workers (FEW). The project is a multidisciplinary research collaboration between NYU Silver, NYU Grossman School of Medicine, and Northern Manhattan Improvement Corporation (NMIC), a large community-based organization founded in 1979 that operates under a settlement house model to address the needs of vulnerable and under-served communities.
