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 am also the global data systems lead 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.
