I am an epidemiologist with over 20 years experience of living and working in sub-Saharan Africa.  The focus of my research has been implementation science: generating evidence about what works to maximise coverage of high quality health care for women and children, using measurement to inform implemention and adjust programming.  

I lived in The Gambia at the Farafenni Medical Reseach Centre site 1990-95 working for Harvard School of Public Health; in Ifakara, Tanzania 1997-2000 working for Ifakara Health Institute and Swiss Tropical and Public Health Institute; and in Kilimanjaro Region, Tanzania 2001-07 working for LSHTM and IHI. Since 2007 I have been based at LSHTM in London while continuing to travel and work in sub-Saharan Africa. 

Currently I am the Principal Investigator of the IDEAS phase 2 project and the Multiple Micronutrient Supplementation in Ethiopia project; and co-editor of the journal Tropical Medicine & International Health.

I have been providing support to students on the MSc Public Health for Development (previously Public Health in Developing Countries) since 2007, and am co-module organiser for the statistics and epidemiology module Analysis and Design of Research Studies at LSHTM.


I am motivated by efforts to improve the coverage of high quality reproductive, maternal, newborn and child health care, primarily in sub-Saharan Africa. My research has included investigations into women's preferences and priorities for fertility control, testing delivery strategies of insecticide treated mosquito nets for the prevention of anaemia and malaria in pregnancy, and understanding the effectiveness of innovations designed to improve maternal and newborn health.  Through this work I have emphasised the use of evidence for evaluation concurrently with its use for programme improvement, working with project, district and national level actors to support data-informed decision making.    I currently supervise three PhD students, all of whom investigate issues of measurement or health care delivery for girls, women, and newborns in low and middle income settings.
