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, hypertension, diabetes, chronic kidney disease, end-stage renal disease, cancer, liver disease, and influenza vaccination and infection. 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 and captured in the HIV Care Continuum.

My methodologic expertise is in designing studies in longitudinal cohort collaborations. I serve as the co-director of the North American AIDS Cohort Collaboration on Research and Design (NA-ACCORD), which is a collaboration of more than 20 longitudinal HIV cohort studies of adults with individual-level harmonized data. The NA-ACCORD is the North American region of the International Epidemiologic Databases to Evaluate AIDS (IeDEA) network. I have the privilege of sharing that expertise as a member of the Environmental Influences on Childhood Outcomes (ECHO) Data Analysis Center. I am growing my content area of expertise in field of children's health.

Other research interests include health disparities in special populations, the development of data visualization tools, descriptive epidemiology using large data, and causal inference of treatment effects.
