Academic Clinical Lecturer
I am an NIHR Academic Clinical Lecturer in the Nuffield Department of Primary Care Health Sciences at the University of Oxford. My research is based in South Africa and the UK, and focussed on management of infectious diseases in primary care. In Oxford I work in the Infections, Respiratory and Acute Care team and the NIHR HealthTech Research Centre in Community Healthcare. I am also an Honorary Associate Scientist at the Centre for the AIDS Programme of Research in South Africa (CAPRISA).
At CAPRISA, I primarily work on the SHAPE study; a collaboration with South African primary care services which uses de-identified routine data to evaluate the HIV/TB programme. I have been co-PI or co-Investigator on several randomised controlled trials of point-of-care HIV viral load and point-of-care urine tenofovir adherence tests, including the POwER and PHILA studies, and the US NIH funded STREAM and STREAM-HIV trials.
I have been heavily involved in COVID-19 research. I was a co-investigator and trial management group member for the PANORAMIC and PRINCIPLE trials, the UK national platform adaptive trials of antivirals and repurposed medications to treat COVID-19 in the community.
I previously worked at CAPRISA as a Research Clinician and Project Manager. I completed UK General Practice (Family Medicine) specialty training through clinical placements in the London Deanery, UK and Bethesda Hospital, South Africa, before doing the MSc in Public Health in Developing Countries at the London School of Hygiene & Tropical Medicine, and then a DPhil in Primary Care at the University of Oxford.
My work has been supported by funding from Wellcome, the Bill & Melinda Gates Foundation, the UK Global Challenges Research Fund and the National Institute of Health and Social Care Research (NIHR).
I am keen to discuss potential DPhil/PhD projects around primary care, HIV and global health.
