My lab studies the molecular processes that generate genetic variation, and also the consequences of such variation in humans. We use a variety of genomic and transcriptomic approaches to study susceptibility and resistance to disease, both infectious and genetic, and to show how infectious diseases have long acted as a potent selective force in the shaping of the dynamic human genome.
Susceptibility to HIV infection and AIDS. Since the discovery in the 1990s of the first genetic variants that confer protection against HIV infection and the progression to AIDS, my lab has been working to identify additional genes with similar effects. We study this in humans and in a rhesus macaque experimental system.
Cardiovascular complications of HIV therapy. The introduction of Highly Active Antiretroviral Therapy (HAART) has transformed the lives of many HIV-positive individuals. For some individuals, however, HAART carries a risk of cardiovascular side-effects. HIV infection itself can contribute to cardiovascular disease risk, and we are investigating the extent to which host genetics, HIV infection, and HAART interact to give rise to cardiovascular disease in patients enrolled in the Multicenter AIDS Cohort Study (MACS) / Womens Interagency HIV Study (WIHS) Combined Cohort Study (MWCCS).
Epigenetics and aging in chronic HIV infection. Due to the success of therapy, many HIV+ individuals are living longer lives, but some are now showing diseases of aging at unexpectedly younger ages. We are examining the impact of epigenetic factors, such as DNA methylation, on this process.
