I am a clinician and epidemiologist with an interests in infectious diseases and vaccinology. I trained in Infectious Diseases in London and Newcastle and in Epidemiology at LSHTM. Since 1993 I have worked almost continuously at the KEMRI-Wellcome Trust Research Programme in Kilifi, Kenya both as researcher and clinician. Between 1998-1999 I spent two years at the Respiratory Diseases Branch of the US CDC in Atlanta. Between 1998 and 2012 I was based at the Nuffield Department of Clinical Medicine in Oxford; since 2013 I have been based at the School. Since 2016 I have been supporting the development of a new research centre, the Hararghe Health Research partnership, in Harar, Ethiopia - a collaboration between LSHTM and Haramaya University. I have directed the NIHR Health Protection Research Unit in Immunisation since 2014 and, from 2013-2023, I was a member of the UK vaccine policy committee, JCVI. I continue to do vaccine policy work on the WHO strategic advisory group of experts in vaccines and immunisation.

Teaching
Each summer, since 2014, I have co-directed a two week intensive short course with Stefan Flasche under the title: "Epidemiological Evaluation of Vaccines: Efficacy, Safety and Policy". I lecture on infectious diseases, surveillance, disease burden assessment, pneumonia and pneumococcal diseases on a variety of MSc modules including Extended Epidemiology, Epidemiology of Infectious Diseases and Vaccine Immunology.
