Research Summary
How our brain is developed and evolved remains a major question in biology, and abnormal development of the human brain can cause autism, epilepsy and intellectual disability. We study fundamental mechanisms of brain development and disorders, and our specific interests include: tracing cell types and lineages in mammalian brains, genetic mechanisms of neuronal type specification, and roles of RNA splicing diversity in neural development and diseases. We develop and apply single cell approaches, animal models, and functional genomics to address these questions.
