I joined LSHTM in 2005, as a statistician at the Mwanza Intervention Trials Unit (MITU) in Tanzania. I am currently based at the Africa Health Research Institute (AHRI) in rural KwaZulu Natal, South Africa, as the head of the Data Science Unit. I continue to collaborate with colleagues in Tanzania on HPV research.
Before joining LSHTM, I spent seven years as a statistician in the pharmaceutical industry. I have an MSc in Epidemiology and an MSc in Statistics, and completed my PhD at LSHTM in 2025. My first degree is in Geology, and before studying epidemiology, I worked as a geophysicist.
Affiliations
Teaching
I was the Programme Director of the MSc Medical Statistics from 2018-2023 and have been chair of the Med Stats MSc exam board since 2023. I am a co-module organiser for Foundations of Medical Statistics, and Research Design and Analysis. I also teach on Introduction to Statistical Computing, and the Advanced Course in Epidemiological Analysis (ACEA) short course.
Research
I have been the senior statistician on a number of complex HIV prevention trials and HPV vaccine trials. I am the joint Principal Investigator on two large ongoing trials of single-dose HPV vaccination in Tanzania, one of which contributed to the evidence base for WHO’s recent recommendation that the HPV vaccine dose schedule be updated to allow countries to choose a 1-dose schedule. In addition to my research on HPV in Tanzania, I am a coinvestigator and lead statistician on a number of HIV treatment and prevention trials at AHRI, including a cluster-randomised trial to investigate network-delivered HIV self-testing, a stepped-wedge trial to evaluate a community-based biosocial HIV prevention intervention, and a stepped-wedge trial of a mobile phone-based intervention to help adolescents living with HIV transition to adult care.
