Research Summary

My research focuses on understanding the natural history of viral infections, particularly HIV and the hepatitis viruses, in both domestic and international settings. The ALIVE (AIDS Linked to the Intravenous Experience) study is a long-standing and productive cohort that characterizes the natural history of HIV infection among intravenous drug users in Baltimore, MD. Our research in ALIVE ranges from pathogenesis to clinical to behavioral. In particular, I focus on the non-AIDS outcomes of HIV including cancer, liver and lung diseases. I also work on related topics with international collaborators, primarily in Africa. The interaction of viral, environmental and genetic factors is an important determinant in progression of many viral diseases. My research employs genetic, proteomic, and other novel laboratory and imaging methods to help understand and identify individuals at greatest risk for clinically relevant outcomes from HIV, HBV and HCV infections. The long-term goal of this research is to translate these markers into targeted interventions to help reduce the burden from these infections.
