Dr. German (she/her) directs the HBS doctoral program and teaches the JHSPH doctoral seminar in mixed methods research. She directs the JHSPH Certificate Program in LGBTQ Public Health and coordinates the JHSPH LGBTQ Working Group. Her research draws from interdisciplinary perspectives and uses qualitative and quantitative methods to understand and address the social and structural context of health behavior and disease transmission, with particular emphasis on applied research related to drug use, HIV transmission, and mental health among marginalized populations in Baltimore and throughout Maryland. She has a long history of behavioral research, harm reduction program experience, and collaboration with community organizations and health departments. Current research interests include: social network resources, social stability, and HIV transmission; individual and community level implications of traumatic and stigmatizing experiences; and implementation science to inform strategies for addressing social determinants of health.

As Principal Investigator for BESURE, the Baltimore arm of CDC’s National HIV Behavioral Surveillance Project, Dr. German oversees annual community-based mixed methods data collection to measure prevalence and trends over time in HIV, health and social issues, health-related behaviors and access to services among people who inject drugs, men who have sex with men, and individuals at increased risk of heterosexual HIV transmission, as well as a complementary set of projects focused on transgender health (CLEAR: Communities Leveraging Evidence for Action and Research). As Co-PI for the Statewide Ethnographic Assessment of Drug Use and Services (SEADS), a large qualitative study designed to understand drug use, barriers to service utilization, and potential for harm reduction expansion across Maryland, Dr. German oversaw data collection among people who use drugs and stakeholders across the 18 Western, Central, and Eastern Shore counties. Publicly accessible SEADS reports are available here:
