Jamie Rossjohn is National Health and Medical Research Australia Fellow at Monash University. He has retained substantial links with UK-based science since embarking on investigations in Australia particularly with Cardiff University, through which he has published frequently in premier journals. This includes work on Natural Killer cell receptors, HLA-linked drug hypersensitivities, innate-like T-cell recognition of vitamin B metabolites, and autoimmunity and MHC-mediated immunity. Professor Rossjohn has consistently fostered collaborations across the UK, spanning from his early work on pore-forming toxins and his pioneering work on lipid-mediated immunity, and he routinely acts as a reviewer for the Wellcome Trust and the MRC.
