Dr. Weintraub  leads the Cases in Global Health Delivery, a collection of free, Harvard Business School-style teaching cases that allow readers and students  to examine real-life programmatic, organizational, and policy-related decisions in low resource settings. The Case library builds critical thinking and analytical skills and continues to be integrated at Schools of Medicine, Business and Public health. In the midst of the pandemic, Dr. Weintraub expanded her portfolio, building tools adopted by State governments and the CDC  to plan for the equitable distribution of COVID-19 vaccines.
