Investigator Biography

Graham studied Biochemistry at the University of Birmingham before completing a PhD in yeast pheromone signalling with John Davey at Warwick. He continued to work at Warwick as a post-doc studying pro-hormone convertases before securing a 5-year independent fellowship funded through the NHS. This project enabled him to return to his interest of GPCRs. He was appointed a lecturer at Warwick in 2006. In 2015 he was appointed to a lectureship in the Pharmacology Department, the University of Cambridge. He is a full member of the British Pharmacology Society and regularly attends meetings both in the UK and Australia. He has a long-standing collaboration with Dr Simon Dowell at GlaxoSmithKline. His group is interested in RAMP-mediated signalling bias of family B GPCRs.
