Dr. Jung Weon Lee is a Professor at the Department of Pharmacy, College of Pharmacy, Seoul National University (SNU), Korea. He earned a Ph.D. in Pharmacology, University of North Carolina at Chapel Hill, NC, USA. He had a postdoc period at Memorial Sloan-Kettering Cancer Center, New York, NY, USA for cell adhesion signaling. In 2001, he moved back to Korea as an Assistant Professor at the College of Medicine, SNU, Korea. In 2009, he moved to the Department of Pharmacy, SNU and is now a Full Professor. His research has focused on how cellular functions including morphological changes, epithelial–mesenchymal transition, migration, and invasion could occur at the molecular levels. Such mechanistic insights on cell functions can lead to the development of the reagent(s) to inhibit the abnormally-metabolic, fibrotic, tumorous cell functions. These days, his research group mostly focuses on the roles of a tetraspanin, TM4SF5, in fibrosis, tumorigenesis, and metastasis and on the anti-TM4SF5 reagents to block TM4SF5-mediated diseases including metabolic disorders, fibrosis, and cancers in either 2D or extracellular matrix-surrounded 3D culture conditions via biochemical, cell biological, and molecular biological approaches in addition to animal models and clinical samples for the fibrotic and tumor models or patients (Lab homepage: http://jwl.snu.ac.kr/).
