My research interests are in child and adolescent health and nutrition.

I am the statistician for the MBIRA prospective observational cohort study, which is investigating the effect of third generation cephalosporin resistance in Gram-negative bloodstream infections in African hospitals in 2021 using the GLASS methodology.

I work closely with colleagues at the National Institute of Medical Research in Mwanza, exploring interrelationships between diabetes, gut health and HIV in Tanzanian adults.

I was lead statistician for the BREATHE trial which presented primary results at CROI 2020. The trial was conducted in Zimbabwe and Malawi and investigated the use of azithromycin for the treatment of chronic lung disease in HIV-infected adolescents, funded by the Medical Research Council of Norway.

I currently have four Zimbabwean doctoral students seeking to determine how perinatal HIV infection affects bone health in adolescents and pre-menopausal women. I am not currently taking on new students. I have previously supported doctoral students who quantified maternal infections and compared cognition and the brain structure of children born uninfected to women living with HIV compared to children unexposed to HIV.

Some highlights of my career so far have been as lead statistician for the NUSTART (nutritional support for adults starting antiretroviral therapy) trial in Tanzania and Zambia which  investigated the effect of nutritional supplements for malnourished HIV patients on mortality. I was also lead statistician for the cluster randomised trial of intermittent preventive therapy for the control of malaria in Ugandan school children. I  supported the Bioko Island Malaria Control Initiative, investigated the effect of Vitamin D supplementation on the hospitalisation rates of infants up to six months of age in Delhi, I showed that TB cure rates could be improved in Senegal by decentralising care, and investigated the epidemiology of rotavirus in an urban slum in India.
