My background is in Mathematics and Medical Statistics. I joined the LSHTM in October 2008 after previously working in statistical genetics at the Institute of Cancer Research.


Faculty of Epidemiology and Population Health
Department of Infectious Disease Epidemiology


Malaria Centre
Statistical Methodology
Tuberculosis (TB) Centre


I co-organise (with Rein Houben and Lois Kim) the distance-learning module EPM202 (Statistical Methods in Epidemiology). I also teach on the in-house courses Statistics for Epidemiology and Population Health (STEPH), Statistical Methods in Epidemiology (SME) and Advanced Statistical Methods in Epidemiology (ASME). I am a tutor for both the Epidemiology and Medical Statistics MSc courses.


I am a member of the Tropical Epidemiology Group (TEG), and am co-theme leader (with Tansy Edwards) for TEG's work on emerging and neglected diseases. My current research focuses on the design and analysis of intervention and observational studies in the fields of helminths, tuberculosis and child health, with a particular interest in cluster randomised trials.

I am the trial statistician on the Entebbe Mother and Baby Study (EMaBS). This trial, located in Entebbe, Uganda, investigates the impact of helminth infections and their treatment during pregnancy on birth outcomes, illness and allergy events during infancy, and on immunological responses to childhood vaccinations.  I am also the statistician for the Lake Victoria Island Intervention Study on Worms and Allergy-related diseases (LaVIISWA), a cluster randomised trial, taking place in the Koome islands, Uganda, investigating the effect of intensive anthelminthic treatment on allergy outcomes. I additionally provide statistical supervision and capacity building to other members of the LaVIISWA and EMaBS teams.

I am a co-investigator on an MRC programme grant, which aims to understand population differences in vaccine response and to determine how vaccine effectiveness can be optimised for tropical low-income countries (LICs), based on trials in urban and rural populations in Uganda.

I am co-PI and trial statistician on the HomeACF Study, a household cluster randomised trial of active case finding for HIV and TB, preventive treatment against TB, and ART initiation to prevent TB disease and transmission, in South Africa. I am also the trial statistician for the ABAaNA early intervention trial, which investigates the feasibility and effectiveness of early intervention for young infants at high risk of neurodevelopmental delay and disability in Uganda.
