Junfeng Zhao got his PhD degree at Nanyang Technological University (Singapore) in 2010. After postdoctoral research at Nanyang Technological University and University of Muenster (Germany) from 2010 to 2013, he joined The University of Hong Kong as a research assistant professor. He started his independent career at Jiangxi Normal University (China) as a full professor in 2014 and stayed there till 2020. In 2021, his research group moved to Guangzhou Medical University (China). His research interest focuses on green peptide synthesis, precise modifications of peptides and proteins, and peptide drug discovery. His research group disclosed that both ynamide and allenone could be used as coupling reagents to facilitate peptide bond formation in a racemization/epimerization-free manner with active vinyl esters as stable intermediates.
