Prof. Jie Jack Li from University of San Francisco visited School of chemical Biology and Biotechnology and gave us a series of lectures on the history of drug discovery. Prof. Li is not only a chemist, but also a writer. He has published more than 20 chemistry books. Among those books, is most familiar one to us. Prof. Li is really passionate about teaching and well loved by students. After 5 lectures, we became to understand more about drug discovery and reaction mechanisms. We warmly welcome Prof. Jie Jack Li to visit us again next summer!
