Choi’s lab of Washington University School of Medicine, and served as professor at Department of Pharmacology, Ajou University School of Medicine for 1995-2011. I had served as director of Research Institute for Neural Science and Technology, Center for the Study of Interventional Therapy of Stroke and Alzheimer’s Disease, and Anti-Alzheimer’s Drug Development Research Center. I was appointed as a director of Innovative Research Project for CNS drug Discovery and Development in 2014 and National Drug Development Project for the treatment of Stroke in 2017 in China. I published more than 90 papers in high impact journals including Science, Journal of Cell Biology, and Journal of Neuroscience. I and my colleagues founded GNT Pharma in 1998 and invented drug candidates for the treatment of stroke and neurodegenerative diseases with more than 70 issued patents.
