I am a medical statistician with a focus on the epidemiology and control of infectious diseases, in particular, the evaluation of treatment and intervention strategies for neglected diseases, emerging infectious diseases and outbreaks.

I have been at LSHTM since 2003 as part of the MRC International Statistics and Epidemiology Group (https://www.lshtm.ac.uk/research/centres-projects-groups/mrc-internatio…), a group of statistical epidemiologists specialising in studies on the epidemiology and control of major public health problems of low and middle income countries, in particular Africa and Asia, with a major focus on HIV, tuberculosis, malaria and neglected tropical diseases, and a special emphasis on intervention studies.

Teaching

I am a co-organiser of Analysis and Design of Research Studies with Professor Tanya Marchant, a core module for MSc students in the Faculty of Infectious Tropical Diseases. I am also a co-organiser of the Masters thesis program for the Distance Learning MSc in Epidemiology.

I teach on a variety of modules for two Distance Learning MSc courses (Clinical Trials and Epidemiology) including Basic Statistics for Clinical Trials and Advanced Statistics Methods in Epidemiology. I have developed teaching materials and delivered lectures for short courses at international collaborating institutions on statistical methods and clinical trials.

Research

I have extensive experience in the design and analysis of individually randomised, multi-centre treatment trials for visceral leishmaniasis; cluster randomised trials of mass drug administration with azithromycin for trachoma control and large-scale epidemiological studies of infectious and non-infectious diseases. More recently I was a co-investigator and statistician for two treatment trials of convalescent plasma for the treatment of Ebola Virus Disease in Guinea (www.ebolatx.eu) and Sierra Leone.

Currently, I am the lead statistician for the evaluation of a heterologous, two-dose preventive Ebola vaccine in DRC; a multi-centre randomised controlled non-inferiority trial of treatments for plague in Madagascar; a TB treatment cohort in the Philippines investigating the impact of co-morbidities including diabetes and malnutrition and a multi-centre randomised controlled trial evaluating community-based nutritional intervention for under 5 year olds with severe acute malnutrition in India.

I am committed to working closely with international collaborators in the areas of research, teaching and professional development; I was previously a visiting scientist based within research organisations in Kenya (2010-2013) and since 2018, I have a part-time Associate Professor secondment at Nagasaki University, Japan, based in London with time spent in Japan.
