Alejandra Tomas is a molecular cell biologist and Senior Lecturer at the Department of Metabolism, Digestion and Reproduction, Imperial College London. She obtained a PhD in Biochemistry from University College London and spent several years in Switzerland working on the study of membrane trafficking processes in pancreatic beta cells, before returning to the UK, first to her Department at UCL, and then to lead a laboratory at Imperial following the receipt of an MRC New Investigator Award in 2015. 

Her most significant research outputs include the identification of the main incretin receptor trafficking regulators in beta cells, the characterisation of biased GLP-1R agonists with improved therapeutic profiles, and the study of the influence of the lipid microenvironment on the regulation of incretin receptor outputs, with papers in high-impact journals such as PLoS Biology, Nature Communications, Diabetes and Science Advances. She has recently joined the Society for Endocrinology Metabolic and Obesity Network group to serve as scientific advisor in these areas.
