SciVal Experts Research Profile


PhD, Johns Hopkins Bloomberg School of Public Health, 2008
MPH, Johns Hopkins Bloomberg School of Public Health, 2005


My main research interests is aging in the context of human immunodeficiency virus (HIV) infection. Non-AIDS related aging outcomes of interest include cardiovascular disease, diabetes, end-stage renal disease, cancer, liver disease, and influenza vaccination and infection. AIDS-related aging outcomes include immunologic and virologic response to highly active antiretroviral therapy (HAART). My secondary interest is in monitoring the quality of HIV cinical care in the United States using longitudinal cohort studies by assessing trends in treatment, viral load, CD4 count, and other indicators specified in the National HIV Strategy.

Other research interests include sex-based differences in HIV, health disparities in special populations, and epidemiologic methodology issues in causal inference of treatment effects. I investigate these topics using nested study designs in the MACS, WIHS, ALIVE and NA-ACCORD cohorts of HIV-infected and -uninfected individuals.
