Research interests
I am interested in the dynamics of vaccine-preventable human infections in low-income nations.
Though largely controlled in developed countries, many vaccine-preventable human infections are major public health issues in many areas of the world. Specifically, parts of Africa have extremely high incidence of the directly transmitted diseases measles and meningococcal meningitis. For directly transmitted pathogens, transmission patterns are rooted in human mixing behavior across spatial scales. Identifying spatial interactions that contribute to recurring epidemics will help define and predict outbreak patterns. My work examines the underlying mechanisms for spatial heterogeneities in host disease burden and risk across spatial scales, from regional dynamics to seasonal outbreaks in individual cities by assessing regional variations in movement and contact patterns relating to outbreaks as well as mechanisms for seasonal forcing in cities.
