In our laboratories, we use every possible tool to attack diseases. Cutting edge ideas, research and equipment allow us to discover the mechanisms of genes and epigenes, pathogens, and infection itself. In the field, we discover ways to improve health on a population level, in developed and developing nations, in people of every age, ethnicity and status. As the oldest institution of its kind and the largest school of public health in the world, the Bloomberg School will continue to lead the charge toward better health for everyone. We now serve more than 2,000 students from 87 countries, with nearly 600 full-time faculty. Our scientists conduct ongoing.
