Dr. Chung is an assistant professor in the Department of Biological Sciences at KAIST in South Korea. He earned his B.S degree at Seoul National University in South Korea and received his Ph.D. in developmental genetics in 2009 at the University of California, San Francisco. After completing his Ph.D., he worked as a postdoctoral researcher with Dr. Ben Barres at Stanford University. During his postdoctoral work, he found that astrocytes, the most abundant cell type in the central nervous system, actively contribute to the activity-dependent synapse elimination that refines neural circuits during development by phagocytosing synapses via the MEGF10 and MERTK phagocytic pathway. In 2016, Dr. Chung started his own laboratory at KAIST, where he is continuously working on the molecular mechanisms and physiological impacts of astrocyte-mediated synapse elimination in healthy and diseased brains.
