I joined LSHTM in 2005, and was based in Mwanza, Tanzania, until September 2008, when I returned to London. Before joining LSHTM, I spent seven years as a statistician in the pharmaceutical industry. I have an MSc in Epidemiology and an MSc in Applied Statistics. My first degree is in Geology, and before studying epidemiology, I worked as a geophysicist. In addition to Tanzania, I have lived and worked in Nigeria, Thailand and Peru.


Department of Infectious Disease Epidemiology
Faculty of Epidemiology and Population Health


I am a module organiser for Research Design and Analysis, with Emma Slaymaker.  I also teach on Statistics for Epidemiology and Population Health (STEPH), Statistical Methods in Epidemiology (SME), Advanced Statistical Methods in Epidemiology (ASME) and the distance learning MSc in Clinical Trials.


I am a member of the Tropical Epidemiology Group in the Department of Infectious Disease Epidemiology. Since joining LSHTM, my main research interest has been in the epidemiology of HIV and other sexually transmitted infections in sub-SaharanAfrica, with a focus on the design and analysis of intervention trials. 

From 2005–2008, I was based in Mwanza, Tanzania, with the LSHTM/Tanzanian National Institute of Medical Research (NIMR) collaborative research programme (now the Mwanza Intervention Trials Unit, MITU); I continue to provide statistical support to researchers in Mwanza.  I have been the trial statistician on a number of complex HIV prevention trials and HPV vaccine trials inTanzania.  I am also the trial statistician for a cluster-randomised trial inUgandaandTanzaniawhich aims to improve the health systems response to chronic diseases, including HIV. 

I currently have two main areas of interest, HPV epidemiology and the interaction between HPV and HIV infection, and the role of the vaginal microbiome in determining susceptibility to HIV and other STIs, particularly around the time of sexual debut.  I am particularly interested in methodological issues related to measurement of adherence in HIV prevention trials   I am also interested in statistical methods for analysing vaginal immunological biomarkers.
