I am an infectious disease epidemiologist interested in the roles of sanitation, hygiene, and water for the control of neglected tropical diseases. I am currently working on the TUMIKIA Project to evaluate the impact of alternative deworming delivery and treatment strategies on soil-transmitted helminth infection in Kenya. I also develop and manage global data systems for DeWorm3.
I have a Bachelor’s degree in history from Kenyon College and a Master of Health Science degree from the Johns Hopkins Bloomberg School of Public Health. I completed my PhD in Epidemiology at Emory University.
My research focuses on the influence of context upon both behaviours and diseases related to sanitation, hygiene, and water. For my PhD, I used multilevel modelling of trachoma impact survey data from Amhara Region, Ethiopia to examine the effect of community sanitation levels on active trachoma and soil-transmitted helminth infections in children. Also, using a geographic information system to combine survey data with compiled information on environmental and sociodemographic factors, I examined their relationships with community levels of sanitation. My earlier research in Lima, Peru examined the influence of water and sanitation availability in periurban households upon mothers’ handwashing behaviour at critical moments.
