While at IHME, Ruben worked on the Access, Bottlenecks, Costs, and Equity research team. This project aims to generate evidence around the cost-effectiveness and efficiency of health systems, primarily through a survey of hospitals and health clinics in seven countries. Following the Post-Bachelor Fellowship, Ruben continued to pursue his interests in health systems and evidence-based decision-making at PATH.
