I am a Senior Clinical Research Fellow in Vaccinology and Honorary Consultant at Imperial College London. I studied as an undergraduate in Medicine at Newnham College, University of Cambridge and Imperial College London, before qualifying as a junior doctor and undertaking specialist professional training in Genitourinary and HIV Medicine. 

I am the clinical Principle Investigator across the diverse portfolio of vaccine studies at the Imperial NIHR Clinical Research Facility Working closely with Professor Robin Shattock in the Department of Infectious Disease, this work involves the crucial early-stage development of potential vaccines against pathogens such as HIV and chlamydia and includes first-in-man studies of potential vaccines. I also work closely with the Oxford Vaccine Group and Jenner Institute developing vaccines against diverse infections including ebola and malaria.

I hold a St. Mary’s Development Trust award for human vaccine research to investigate how T cells orchestrate the response to immunogens in the blood and secondary lymphoid tissue. This work is particularly important in helping us to design sophisticated vaccines that can induce the broadly neutralising antibody response required to protect against difficult targets such as HIV.

In 2019 I was awarded the Margaret Johnson prize by the British HIV Association for my work on influenza vaccine.
