Dr. Dasgupta’s current research interests involve understanding how women who are engaged with the criminal justice system contend with HIV risk (via unsafe sex and drug use), and gender-based violence.


Kristi Stringer, Ph.D.

Dr. Stringer received her Doctorate in Medical Sociology (2017) and her Master of Arts degree in Sociology (2012) from the University of Alabama at Birmingham (UAB). She earned her Bachelor of Science in the field of Psychology at Middle Tennessee State University in 2009. During her tenure at UAB, Dr. Stringer was an AHRQ pre-doctoral fellow at the Center for Outcomes and Effectiveness Research and Education in UAB’s Division of Preventive Medicine and was awarded a Ruth L. Kirschstein NRSA Individual Predoctoral Fellowship (F31) from the National Institute of Drug Abuse in 2014. Dr. Stringer’s research agenda focuses on the impact of health related stigmas on the HIV treatment cascade and the development of stigma reduction interventions aimed at increasing HIV prevention and treatment adherence behaviors. Her dissertation research utilized a mixed-methods approach to understand the adverse effects of substance use stigma and HIV-related stigma on adherence to antiretroviral medications and retention in HIV care among drug involved people living with HIV (PLWH). During her post-doctoral training at Columbia University, Dr. Stringer plans to adapt a stigma reduction intervention to address health related stigmas experienced within healthcare environments among drug involved PLWH in Kazakhstan through Columbia’s collaboration with the Global Health Research Center of Central Asia (GHRCCA).
