My research is focused on studying HIV-1 pathogenesis, transmission and prevention using single cell in situ analyses and in vivo SIV-rhesus macaque and humanized-BLT (bone marrow liver and thymus) mouse models of HIV-1 infection. I have published extensively on HIV/SIV transmission, pathogenesis and prevention, including one paper in Science and two papers in Nature as the leading author.

The Early Events Determining SIV Rectal Transmission
Anal intercourse is a common mode of HIV-1 transmission, particularly for men who have sex with men, however, many fundamental and mechanistic questions remain. The objective of this study is to understand the early events in HIV-1 rectal transmission and to gain new insights, which will potentially lead to new intervention strategies, including vaccines and topical microbicides optimized for rectal use.

The Early Events of SIV Rectal Transmission in Indian and Chinese rhesus macaque
Anorectum is a major HIV transmission route, especially for men who have sex with men. Study of the early
events of rectal transmission of SIV in rhesus macaques of distinct origin will gain new insights into how to prevent HIV-1 rectal
transmission, since HIV transmission occurs in individuals of distinct and diverse origin.

We propose to test this hypothesis with three specific aims. Specific Aim 1, to control the replication of
novel Δnef-LAV in vitro, of which we will apply and further optimize blank codon suppression strategy and incorporate suppression
tRNA*-aaRS* pair into the HIV-1 genome to control HIV-1 replication by supplementing or withdrawing UAA* in mammalian cells in vitro.
Specific Aim 2, to control novel Δnef-LAV replication in vivo, of which we will compare and contrast the in vivo replication capacity and
kinetics of the novel Δnef-LAV that has passed multi-cycle replication tests in vitro in the Specific Aim 1 with conventional Δnef-LAV
using humanized-BLT mice. Specific Aim 3, novel Δnef-LAV in vivo protection, of which we will compare the protection rate of novel
Δnef-LAV vs. conventional Δnef-LAV against HIV-1 rectal challenge using hu-BLT mice.

B-cell Biology of Mucosal Immune Protection from SIV Challenge
The Emory Consortium for B-Cell Biology of Mucosal Immune Protection from SIV Challenge, using highly
collaborative approaches, will define, through advanced immunological and systems biology approaches, the underlying mechanisms for
enhanced antibody avidity and protection.

Early Innate/IgA Anti-HIV/SIV Response in Exposed and Uninfected
Determining the presence of local cellular cervical tissue infiltrate, IFN-mediated gene expression, and mucosal anti-HIV IgA antibody responses in 3 well-defined groups of women with differential exposure risk based on sexual activity/partner 2. Determine if repeated cervico-vaginal exposures to non-infectious SIV E660 exposures induce a persistent innate cellular infiltrate (plasmacytoid DCs, NK, macrophages) that in combination with mucosal SIV-specific IgA antibody levels directly correlate with infectivity thresholds with SIV mac251.
