I currently work at LSHTM as a Research Fellow in the Environmental Health Group which is the focus of the School's work on water, sanitation and hygiene (WASH) and health, and currently includes approximately 30 researchers and support staff working on range of research areas.

For the last five years, I have been working on the evaluation of WASH interventions in humanitarian crises. I have a particular interest in programme design and how to use both quantitative and qualitative data from existing monitoring and evaluation frameworks to improve programme implementation. I am also carrying out a part-time PhD along with being a Research Fellow at LSHTM. My PhD research is focussed on the epidemiology of WASH related diseases and the evaluation of WASH in cholera outbreaks in humanitarian crises, collaborating with a range of implementing organisations and multilateral agencies including Médecins Sans Frontières, WHO and UNICEF. 

Prior to joining LSHTM as a researcher, I have worked as a programme manager in multiple non-governmental organisations (NGOs) coordinating WASH, nutrition or HIV/AIDS programmes in Sub-Saharan Africa and Asia. I have a BSc in Biology (University of Nottingham) and a MSc in the Control of Infectious Diseases (LSHTM).
