Katherine Halliday completed her undergraduate degree in Archaeology and Anthropology at the University of Cambridge in 2007, specialising in Biological Anthropology. Her final thesis looked at the impact of chemotherapy and/or health education on reducing geohelminth infections in rural Bangladesh. After my degree she was based at MRC Keneba fieldstation in The Gambia, working as a research assistant on a clinical trial investigating the effects of daily omega-3 oil supplementation in infants on growth, gut integrity and cognitive development. In 2008/9 she took the MSc in Control of Infectious Diseases at LSHTM. My project looked at the epidemiology of asymptomatic Plasmodium falciparum infection in schoolchildren in the highlands of Western Kenya, and its implications for control. Katherine has since worked with KEMRI-Wellcome Trust on The National Schools Malaria Survey in Kenya and she is currently helping to coordinate a cluster randomised trial looking at the effects of school-based Intermittent Screening and Treatment (IST) and enhanced literacy instruction on educational achievement and anaemia in 101 schools in Kwale District, South Coast, Kenya.
