Research Interests
I am interested in developing and applying statistical methods to identify genetic factors influencing complex traits. I participate in collaborative research projects focused on Fuchs endothelial corneal dystrophy, kidney disease in diabetes, abdominal aortic aneurysm, age-related macular degeneration and phenotype severity in cystic fibrosis. I am involved in the Human Genetic Analysis Resourse (H.G.A.R.), a collaborative project that develops statistical methods to analyze genetic data with an eye toward localizing genetic variants that cause disease, and that implements these approaches in the Statistical Analysis for Genetic Epidemiology (S.A.G.E.) software package.
