Our research focuses on defining gene regulatory networks (GRNs) that control neural cell specification, neurogenesis, and the generation of specific neuronal cell types. We are particularly interested in understanding how epigenetic regulation modulates these networks and how their dysregulation contributes to neurodevelopmental disorders and birth defects, including epilepsy, autism spectrum disorder, and neural tube defects. This work uses directed differentiation of human pluripotent stem cells (embryonic stem cells and induced pluripotent stem cells), mouse models, and a wide range of cellular, molecular, and genomic approaches, to define roles for transcriptional and epigenetic regulation in shaping developmental transitions.
