Data Science, Econometrics & Impact Evaluation

I work at the intersection of data science, econometrics, and impact evaluation, building the pipelines, models, and infrastructure that turn messy real-world data into rigorous evidence for governments, researchers, and institutions.

Over 15+ years I've applied this across the World Bank, oTree, and Busara, working on development, governance, and public policy, particularly across the Global South.

Based in Nairobi, Kenya. Avid golfer. Let’s connect!
