Tansy Edwards MMATH MSc

Assistant Professor in Medical Statistics


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


I have been based at LSHTM since 2003 working within the Tropical Epidemiology Group (http://teg.lshtm.ac.uk/), a group of statistical epidemiologists specialising in studies on the epidemiology and control of major public health problems of developing 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. I was based in Nairobi, Kenya from 2010 to 2013.





I am a co-organiser of Analysis and Design of Research Studies with Tanya Marchant, a core module for MSc students in the Faculty of Infectious Tropical Diseases. I also teach on a variety of modules for two Distance Learning MSc courses (Clinical Trials and Epidemiology) including Basic Statistics for Clinical Trials, Data Monitoring and Interim Analysis and Advanced Statistics Methods in Epidemiology. I have developed teaching materials and delivered lectures for short courses in Kenya and Uganda on statistical methods and clinical trials.


I work mainly on research projects relating to trachoma and visceral leishmaniasis. My main interests lie in the design and analysis of cluster randomised trials of mass drug administration for control of neglected tropical diseases and multi-centre individually randomised trials of new treatments for visceral leishmaniasis. I also have experience in the design and analysis of large scale epidemiological studies. I am a co-investigator and statistician on two treatment trials of convalescent plasma for Ebola Virus Disease in Guinea (www.ebolatx.eu) and Sierra Leone.
