Yeon Ha Ju, PhD

She received B.S. degree of biology from Konkuk University and received Ph.D. degree of neuroscience from UST. She has studied the molecular and metabolic mechanism of Alzheimer's disease through reactive astrocytes in Justin Lee's Lab. In Nam lab, she is studying molecular mechanisms of epilepsy and metabolic alterations of neurological diseases using electrophysiology and molecular biology.
