The major research interest of the lab is to understand molecular mechanisms of HIV replication and pathogenesis, and their implications for understanding pathogen-host interactions, immune responses, and disease outcomes. Using biological, genetic, biochemical, and systems biology approaches, we study: 1) HIV replication and pathogenesis in the immune system, gut, and central nervous system; 2) mechanisms and pathways underlying differences in host responses to viral infection and antiretroviral therapy; 3) viral diversity and tropism for specific cell types and tissues; 4) functions of the HIV Env, Vif, and Nef proteins; 5) high-throughput screening assays to identify small molecules that inhibit Vif interaction with its host cell cofactor APOBEC3G.
