Isabel Frost is a fellow at the Center for Disease, Dynamics, Economics and Policy. She gained an MSci in Chemistry from the University of Bristol and went on to complete a DPhil in Systems Biology at the University of Oxford. Her doctoral work used a combination of modelling and wet lab techniques to explore the role of microbial interactions in the evolution of antibiotic resistance. During her DPhil Isabel gained three months of experience at the World Health Organization where she saw the vital role of policy in combating infectious disease. Isabel was brought to CDDEP by the opportunity to work on projects where science and policy overlap and to contribute to the rapidly emerging threat of antimicrobial resistance.
