My research program employs a multifaceted strategy to bridge developmental neurobiology, RNA biology, and evolution. 1) We investigate how cell fates are specified, by studying how progenitor divisions influence development and disease. 2) We study diverse layers of post-transcriptional regulation in neural progenitors. We investigate RNA binding proteins implicated in development and neurological disease. Using live imaging, we also investigate how sub-cellular control of mRNA localization and translation influences neural progenitors. 3) A parallel research focus is to understand how human-specific genetic changes influence species-specific brain development. Our goal is to integrate our efforts across these three major lines of research to understand the intricacies controlling brain development.
