Maheshi received her undergraduate medical training at Christ’s College, Cambridge. She subsequently trained as a junior doctor in Infectious Diseases and General Internal Medicine in Oxford, London and Australia and obtained a DPhil from Wadham College, Oxford.
As a Clinician Scientist at the Oxford Vaccine Group, Maheshi’s research focuses on developing novel vaccines for emerging pathogens including Lassa fever virus and invasive non-typhoidal Salmonella. She has a particular interest in controlled human infection models, both as a tool to understand the pathophysiology of disease and to inform vaccine design.
She leads the UK National Immunisation Schedule Evaluation Consortium and is a member of the Joint Committee on Vaccination and Immunisation (JCVI), advising the UK Department of Health and Social Care on immunisation policy.
Maheshi is the Director of the European Society for Clinical Microbiology and Infectious Diseases (ESCMID) Vaccine Subcommittee.
