My main career goal is to help international development investment make more of a difference. To do so, my work is intended to help improve the logic and evidence that underpins program strategy, selection and design, especially in the sectors that matter most to the poor - agriculture, natural resources, the environment and climate change. My 14 years of experience have focused on quantification of achieved and potential impacts of development investments using novel approaches that draw on tools from different disciplines. My work has included a range of methods (often in mixture), from randomized experiments, to quasi-experimental approaches, bio-economic modeling, and economy-wide modeling for a range of international organizations and donors.
