Dr. Rosenberg's research focuses on studies, methods, and analyses for understanding pertinent epidemiological issues in HIV/STI prevention, such as the racial disparities in HIV/STI among men who have sex with men (MSM) in the United States, surveillance of HIV prevention and care among MSM and persons who inject drugs (PWID), and the impact of care and prevention policies in reducing transmission.

Specific methodological interests include surveillance methods, statistical and network modeling to inform public health policies, and development of software to support research studies. He also applies these methodological interests towards studies of Hepatitis C, Zika, and Dengue viruses. Dr. Rosenberg joined PRISM at its outset in 2008. His primary appointment is in the Department of Epidemiology and Biostatistics, University at Albany School of Public Health, State University of New York. He is also an adjunct associate professor in the Department of Epidemiology, at Emory Rollins School of Public Health.
