I am an Assistant Professor at the Center for Public Health Genomics and the Divsion of Epidemiology and Biostatistics in the Department of Public Health Sciences at the University of Virginia.

My research lies in the areas of mathematical and statistical modeling of biological systems, with an emphasis on 1) analysis of genome-wide association studies in the presence of population admixture, 2) gene-based analysis of rare variants, 3) quantitative trait mapping in experimental crosses, and 4) integrative genomics and pathway analysis.

I am actively involved in genome-wide association analysis of cardiovascular phenotypes and gene-environment interactions studies performed through the Multi-Ethnic Study of Atherosclerosis (MESA), as well as the analysis of stroke data from the NHLBI Exome Sequencing Project.
