 Now, he is  serving at the Scripps Research Institute as Scripps Family Chair Professor of Chemistry.Wong is best known for his original contributions to glycoscience, especially his development of chemo-enzymatic methods for the practical synthesis of oligosaccharides and glycoproteins and the hierarchical and programmable one-pot synthesis method for the rapid preparation of a large number of oligosaccharides.The original synthetic methods developed by Wong along with his work on the development of glycan microarrays for the high-throughput analysis of protein-carbohydrate interaction and the design of glycosylation probes have enabled not only the fundamental study of glycosylation in biology but also the clinical development of carbohydrate-based medicines, including vaccines and homogeneous antibodies for the treatment of cancers and infectious diseases.
