I am a human geneticist, working in common and rare disease since 1993. From 2023 I have led a new team at the Faculty of Medicine, University of Geneva studying the genetics and genomics of common metabolic disease focusing on type 2 diabetes, obesity and related conditions. Our team uses a combination of human genetics, large datasets and clinical studies, working closely with patients and clinicians at the HUG. Prior to my move to Geneva, I was based at the University of Exeter, UK. My research teams have become internationally recognised as world leaders in the genetics of common traits and conditions, contributing to the discovery of the first common genetic variants linked to type 2 diabetes, fetal and childhood growth, and obesity. I have expertise in the genetics of rare and common disease, having obtained my PhD in 1998 with Andrew Hattersley and Sian Ellard identifying mutations in genes causing monogenic diabetes disorders. Prior to that I trained as a diagnostic molecular geneticist with the Oxford Regional health Authority, UK.
