Research Focus

My research focuses on identifying genes responsible for developmental syndromes that affect the face and in generating animal models that will allow us to investigate the cellular and molecular basis of such developmental syndromes. We are currently using next-generation sequencing to identify genes involved in VDEGS and microdeletion syndromes. To create mouse models, we perform gene targeting in embryonic stem cells to generate conditional mutations in the genes of interest. Another major focus in the laboratory is to understand the mechanisms that results in abnormal morphogenesis of the placenta, since such abnormalities can be catastrophic to the growing embryo and mother.
