Wengang Chai

Biography

Dr Chai is a Senior Research Fellow of the Glycosciences Laboratory and Wellcome Trust supported Carbohydrate Microarray Resource, Department of Medicine. As a trained chemist he became interested in the structural aspects of carbohydrate molecules of biomedical importance. After a period of work at the Institute of Chemistry, Chinese Academy of Sciences (Beijing) and the Department of Pharmaceutical Chemistry & NIH National Bio-Organic Biomedical Mass Spectrometry Resource Center, University of California at San Francisco, he joined the Glycosciences Laboratory at the MRC Clinical Research Centre in 1988, which later became part of the Imperial College London. His research programme has been aimed at characterizing the sequences and understanding the roles of oligosaccharide chains of glycoproteins, glycolipids and polysaccharides in recognition systems of biological and medical importance, including: i) the design and application of integrated strategies to tackle the difficult area of structure and function assignments of oligosaccharides, and ii) the development of methods for structural analysis of bioactive oligosaccharides, using mass spectrometry as the principal technique, and their application in different biological settings.  In collaboration with James Beeson (WEHI, Melbourne), he has defined the essential structural motif on chondroitin sulphate A and hyaluronic acid for adhesion of P. falciparum-infected erythrocytes and the key structural requirements on heparan sulphate-like molecules which can block P. falciparum merozoite invasion of erythrocytes.
