Jia-huai Wang is Associate professor at the Dana-Farber Cancer Institute, Harvard Medical School, USA. As a veteran structural biologist specialized in cell surface receptors functioning in immune system and nervous system he has around 140 peer-reviewed papers published, including 11 articles in Nature, Science and Cell. When in China, in the early 1970’s, he was the team member which determined the structure of insulin, one of the world’s first dozen protein structures solved. Since 1988 he has been working at Harvard. As a leading author, he has published a series of extremely important structures, such as the first virus receptor structure CD4, the first cell adhesion interacting complex CD2/CD58, the ground-breaking preTCR-ligand interacting complex and the prototypical axon guidance cue netrin-1 interactions. He has a deep understanding about protein structure and how a protein functions.
