Research Interests

We aim to understand the molecular and cellular basis of human brain development using cutting-edge techniques such as induced neuronal cells and brain organoids derived from human induced pluripotent stem cells (iPSCs), which mimic human brain cells in vitro.  Using these strategies, we seek to untangle the complexity of the developmental neuronal program and synaptic connectivity underlying both normal and diseased human brain functions. We are actively researching to uncover pathophysiological mechanisms in various neurodevelopmental disorders, i.e. ASDs, schizophrenia, and intellectual disability.  We employ a variety of neurobiological techniques including genome engineering, viral strategies, single cell RNA-seq, live imaging and electrophysiological recordings.
