Welcome!
I’m an Economist at Amazon, applying causal inference techniques—both experimental and observational—to quantify advertising effectiveness on Amazon and optimize media investment strategies.
Previously, I worked in East Africa for four years, designing and directing randomized field experiments (RCTs) across Kenya (Economist at CGIAR International Livestock Research Institute (ILRI) for 36 months), Rwanda (Research Associate at Innovations for Poverty Action (IPA) for 10 months), and Tanzania (1 month).
