Philip Bejon
Director Modernising Medical Microbiology
I am Director of Modernising Medical Microbiology, co-leading with Sarah Walker. I was previously Director of the KEMRI-Wellcome Trust Research Programme, a collaborative Programme formed by the Kenya Medical Research Institute (KEMRI), Wellcome and University of Oxford. I am a clinician with specialist training in infectious disease. I have an interest in the evaluation of vaccines, including malaria, yellow fever and Ebola vaccines. I have undertaken studies of naturally acquired immunity to malaria and human challenge models, and have an interest in bone infection and osteomyelitis.
