 Francesca is a computational chemist with over a decade expertise in target assessment, hit identification and lead optimisation. After obtaining a Ph.D. in Biotechnology, Francesca embarked on a distinguished career path. With five years of postdoctoral fellowships Francesca’s work centered on characterising the structural and dynamical properties of complex biological systems, including proteins and protein-ligand complexes, biological membranes and biomaterials. In 2023, Francesca joined Nxera Pharma (formerly Sosei Heptares), a renowned player in the pharmaceutical industry, where she now provides invaluable computational support to a variety of drug discovery campaigns. Prior to her role at Nxera Pharma, Francesca was at the Cambridge Crystallographic Data Centre (CCDC), working closely with software developers to help the development and enhancement of computational tools for drug discovery. Francesca's multifaceted background as a pharmaceutical chemist and her extensive experience across academia and industry positions her as a dynamic and influential figure in the realm of computational drug discovery.
