Led by Dr. Christopher J.L. Murray, IHME has attracted a core of talented researchers who have worked in senior-level positions at the World Health Organization, the World Bank, and in governments all over the world. Over the years, they have created the concepts that have become the foundation for global health, including the disability-adjusted life year, the Global Burden of Disease, and effective coverage. Their work has been cited by researchers more than 32,000 times and has helped guide significant health reforms in Iran and Mexico. Throughout the school year, IHME faculty members teach classes at both the undergraduate and graduate levels at the University of Washington campus and at IHME in downtown Seattle.
