Matthew Call received his Ph.D. in Immunology from Harvard University in 2007, where he worked on T cell receptor assembly and structure with Prof. Kai Wucherpfennig. After completing postdoctoral training in solution NMR with Prof. James Chou at Harvard Medical School, Call moved to Melbourne, Australia, where is currently Associate Professor and Joint Head of Structural Biology at the Walter and Eliza Hall Institute of Medical Research. His work is focused on understanding complex immune receptor structures and relating their architecture in the cell membrane to their signalling mechanisms. The lab uses solution NMR, X-ray crystallography, mutagenesis and biochemical cross-linking to build more comprehensive views of receptor structure and function.
