My research interests are in the fields of micro development and econometrics, with a focus on Sub-Saharan Africa (Kenya, Rwanda, Sierra Leone and Uganda). My main areas of interest are:
- Agriculture (mostly on technology adoption)
- Mobile money (e.g. M-PESA) or more generally financial access (including credit markets and insurance)
- More recently, political economy, including some work on slums and urbanization
