About

I completed my PhD in Immunology at Harvard Medical School and the Dana-Farber Cancer Institute (Boston, MA, USA) and completed postdoctoral training in solution NMR of membrane proteins at Harvard Medical School. I then established an independent research program at WEHI in Melbourne in 2010. My lab has a particular focus on how the membrane-embedded portions of receptors (transmembrane domains) contribute to the structure and function of immune-signalling complexes and other important cellular receptors. These are not mere anchors for extracellular and intracellular domains, but in fact they provide a unique platform for molecular interactions and represent the only direct physical link between ligand-binding and signalling domains across the cell barrier.

We combine biochemical and biophysical methods (both X-ray crystallography and solution NMR) with protein engineering, saturating mutagenesis and cellular and molecular immunology techniques to study the mechanics of receptor activation and the regulation of cell-surface proteins in the immune system. A major focus in recent years has been the development (with computational protein design collaborators) and structural characterisation of synthetic transmembrane domains as tools to control the structures and activities of engineered receptors such as chimeric antigen receptors (CARs) for cellular immunotherapies.
