He did his Ph.D. work in the laboratory of Dr. Iva Greenwald at Columbia University, followed by postdoctoral work with Dr. Gerald Crabtree at Stanford University. He has a long standing interest in understanding genetic pathways that specify cell fates during development, and currently studies the role of microRNAs in regulating the activity of chromatin remodeling complexes during neural development and conversion of non-neuronal cells into neurons. Dr. Yoo’s work is supported by the awards from NIH Director’s New Innovator Award, the Presidential Early Career Award for Scientists and Engineers, the Ellison Medical Foundation and the Edward J.
