I'm a social demographer with interests in 1) the measurement of demographic indicators in countries with limited data, and 2) the impact of social networks on population health. I have conducted the Likoma Network Study, a study that produced a detailed "map" of the sexual networks through which HIV has spread extensively in a small island community of East Africa. My current work focuses primarily on testing new approaches to collecting demographic data in settings where civil registration systems are incomplete. For example, in Senegal, I'm developing new tools to measure age from photographs using computer vision and machine learning. In several other countries (Guinea-Bissau, Malawi, Uganda and Bangladesh), I'm conducting trials of a new questionnaire to measure adult and maternal mortality.
