Sian Clarke BSc MSc PhD

Associate Professor in Malaria Research and Control


BSc Biology, University of Sussex, UK; MSc Epidemiology, LSHTM, UK; PhD Malaria Epidemiology, University of Copenhagen, Denmark.

I have been based at LSHTM since 2002, when I came back to London to join the staff of the Gates Malaria Partnership. I am a founder member of the ACT Consortium, an international multidisciplinary research collaboration which conducts research on the deployment of ACTs for malaria treatment. I was awarded a Wellcome Trust Career Development Fellowship in 2009 to investigate the epidemiology and control of malaria in school-aged children, and was based overseas in Senegal for 3 years between 2010-2014.

I have previously worked with the DBL Centre for Health Research and Development, Copenhagen, Denmark, 1995-2002; and the Communicable Disease Surveillance Centre, Health Protection Agency, London, UK, 1988-1995. 

I am a member of the London International Development Centre.




MSc Epidemiology: Principles and Practice (distance learning)

MSc Public Health in Developing Countries

MSc Control of Infectious Diseases

I am academic co-ordinator of the MSc module on the "Epidemiology and Control of Malaria"


The primary aim of my research is the development and evaluation of disease control strategies to improve health in low-income countries, with a specific focus on malaria.

My current research investigates (i) the impact of asymptomatic malaria infections on anaemia and cognition; (ii) the epidemiology and control of malaria in school-aged children; and (iii) community-based approaches to improve treatment of malaria and other common childhood infections by community health workers and registered drug shops.

Past research has also examined the spatial epidemiology of malaria in areas of seasonal transmission in West Africa, and low and unstable transmission in the East African Highlands.

I have led numerous intervention studies in sub-Saharan Africa, including randomised trials to evaluate the impact of intermittent parasite clearance in schools; seasonal malaria chemoprevention and nutritional interventions in pre-school children; malaria prevention during pregnancy (IPTp and ITNs); and use of malaria rapid diagnostic tests by CHWs and drug shop vendors.

I have worked in The Gambia, Kenya, Mali, Senegal and Uganda.
