PhD, Johns Hopkins University
MS, Harvard University
My research interests are in autism and neurodevelopmental disorders, breast cancer, and chronic disease comorbidity. I direct the Johns Hopkins Center for Autism and Developmental Disabilities Epidemiology whose mission is to advance knowledge on the population distribution and determinants of autism spectrum disorders and other developmental disabilities through establishment of surveillance systems, participation in a collaborative, multi-centered case-control study, and conduct of innovative, Center-specific research. I also have a number of active research projects in the molecular epidemiology of breast cancer and work actively with the Epidemiology department's cancer research group.
