Jean-Ju L. Chung received her bachelors and masters degree from Seoul National University, Korea and her Ph.D. from Johns Hopkins University in 2007. She was a postdoctoral fellow with David E. Clapham in the Department of Neurobiology at Harvard Medical School. She joined Yale's Department of Cellular and Molecular Physiology as a faculty member in September, 2015.

Her research is devoted to investigating cellular signaling via the membrane receptors and ion channels, with a current emphasis on mature spermatozoan motility and fertilization capacity. She has focused her efforts on the primary calcium channel of spermatozoa, CatSper, and has defined its subunits, its distribution in spermatozoa, its function in capacitation, and its effects on fertility. The Chung laboratory applies novel technologies to sperm biology and reproductive research including super-resolution imaging methods, and is continuing to study physiologically relevant molecular changes during mammalian fertilization.
