Research Interests

WHAT CONTROLS STEM CELL BIOLOGICAL BEHAVIOR? We are interested in answering this question about stem cells both during normal embryonic development but also during healing and regeneration. Further, we are analyzing how this control system goes awry during diseases such as developmental disorders and cancer. Our lab studies the molecular programming of embryonic and neural stem cells as well as cancer stem cells. We are studying the genomic and epigenomic events that inflence pluripotency.
