Dr. Abraham an epidemiologist and biostatistician with 14 years of experience working in data coordinating centers of large multi-site observational cohort studies, collaborating with clinical investigators to develop study design and analytic plans, and direct statistical programmers in their data analyses. As the former director of the Wilmer Biostatistics Center, former chair of the data working group for the Multicenter AIDS Cohort Study (MACS), and current head of methodology for the MACS/WIHS Combined Cohort Study, she has expertise in a wide range of methodological areas, data quality issues, and the practical application of statistical tools. Her current research is in aging and sensory loss. She is the PI of the Eye Determinants of Cognition Study and the HIV Vision Study, studies of vision loss and retinal biomarkers. Her methodology foci are data quality improvement, measurement error correction and the handling of missing data. She also has a background in biomedical engineering, which she has applied to clinical research using diagnostic imaging tools to determine current and future disease risk. In addition to sensory loss, she has published extensively in chronic kidney disease and HIV.
