Graham studied Biochemistry at the University of Birmingham before completing a PhD in yeast pheromone signalling 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 progressed through the ranks at Warwick become an Associate Professor before leaving in 2015 to join the Department of Pharmacology at Cambridge, where he is also a Fellow of St John’s College. In 2020, he was promoted to a Readership in Receptor Pharmacology and was elected a Fellow of the British Pharmacological Society. His research group use a combination of pharmacological investigations and mathematical modelling to study factors that control agonist bias at GPCRs. These investigations have enabled him to foster strong collaborations with the pharmaceutical industry (GSK, Takeda and Firmenich) which have recently been enhanced though him being awarded a Royal Society Industry Fellowship to collaborate with AstraZeneca.
