Elizabeth specialises in the design and analysis of cluster randomised and non-inferiority randomised controlled trials. She is a member of the LSHTM Clinical Trials Unit management group. Trials she has worked on include amongst others an adult ICU ECMO trial (CESAR), an RCTs of tight glycaemic control of children in intensive care (CHiP), a factorial-design cluster randomized controlled trial investigating the cost-effectiveness of a nutrition supplement and a physical activity program on pneumonia incidence and walking capacity in Chilean older people (CENEX). She recently advised on the analysis of the HALI trial a cluster randomized trial of intermittent screening and treatment for malaria among school children in Kenya. She is currently the statistician for the AMOXIPEN trial a non-inferiority trial of injectable benzyl penicillin versus oral amoxicillin treatment for severe pneumonia in children in Kenya and for the PRACTECAL trial a non-inferiority phase II – III trial for new treatments for drug resistant tuberculosis.

Elizabeth is currently the Statistician for the IDEAs (Informed Decisions for Actions in Maternal and Newborn Health) project, and collaborates with the Kenya Medical Research Institute (KEMRI) Wellcome Trust Research Programme in Nairobi.

Elizabeth's other research interests include interrater agreement and reliability and the analysis complex interventions.
