Shamiri Institute, Inc

Our mission is to provide at-risk low-income youths in Sub-Saharan Africa and beyond with the tools to improve their life outcomes.

Bobea Group, LLC

Bobea Group is a data-driven agriculture venture management company focused on Sub Saharan Africa (SSA). While agriculture currently has a massive social and economic footprint in SSA—where more than 60% of the population works as smallholder farmers and agriculture accounts for 23% of total GDP—this remains an untapped industry for innovation. Realizing SSA’s full agricultural potential requires significant investment and radical approaches. At Bobea Group, we adopt a data-driven farm-to-fork approach through which we identify the important factors and drivers of the agriculture sector in SSA; find and support deserving small and medium-sized enterprises (SMEs); and achieve financial impact through a holding company model.

GreenChar Solutions, Ltd

Greenchar provided clean household energy solutions to Kenyan households. Specifically, we provided smokeless, high energy, long lasting charcoal briquettes and clean cookstoves. Our briquettes were made from revitalized agricultural wastes thus providing a root to leaf utilization of agricultural crops. Specially optimized for use of the briquettes, our clean cookstoves conserve heat, reduce emissions, and fuel use, enabling us to save time, money, and lives. By transforming the cooking environment, we reduce the devastating effects of deforestation and put a smile on the face of women and children. We hope to be the ultimate provider of clean household energy solutions. 

Harvard Moral Psychology Lab

Social learning is a cornerstone of human thought and behavior: observing what happens to others shapes how we learn and behave. My work, with Lab Pi Fiery Cushman, explores a simple and relatively understudied form of social learning: vicarious reward learning.  Specifically, we build on prior research that shows signatures of “model-free” learning and decision-making in humans. We interrogate the possibility of an analogous mechanism of observational learning. The key property of model-free learning is that actions are reinforced proportional to their history of reward, without taking into account an explicit model of causal dynamics that lead to that reward. We ask whether actions are also reinforced in proportion to the observed history of reward realized by others.
