Yunfei Du obtained his B.S. (Medicinal Chemistry) in 2001 and M.S. (Organic Chemistry) in 2004 at Hebei University, P. R. China. He pursued his PhD in Organic Chemistry under the supervision of Prof. Kang Zhao from 2004 to 2007 and stayed as a faculty member in Tianjin University after PhD graduation. In 2009, he was promoted to Associate Professor, and from 2011 to 2012, he worked as a postdoctoral research fellow with Prof. Richard P. Hsung at the University of Wisconsin–Madison in USA. He was promoted in 2013 to professor in Tianjin University. Prof. Du’s research mainly focuses on synthetic Organic Chemistry & Medicinal Chemistry: (1) Developing novel synthetic methods, including the application of hypervalent iodine reagents, single-electron oxidants and transition-metal catalysts to construct heterocyclic compounds; (2) Developing novel hypervalent iodine reagents and have them applied to organic synthesis; (3) Exploring new synthetic strategies in the synthesis of some drug intermediates and pharmaceutical reagents. He has published about 130 papers in SCI journals and was selected as one of the ‘Highly Cited Chinese Researchers of 2020’ by Elsevier. Dr. Bubun Banerjee received his Ph.D. degree from Visva-Bharati University, Santiniketan, West Bengal, India.
