Rita R. Colwell

Research and Professional Interests

Dr. Colwell has built her career by tackling some of the most important problems in global infectious diseases, especially waterborne diseases including cholera. Her strategy is to take an holistic approach, rather than focusing only on the pathogen and patient. Pandemics, for example, are affected by climate, adverse weather events, ocean circulation, etc, and Dr. Colwell’s research has helped predict outbreaks based on such environmental variables. This pioneering approach is suitable for populations worldwide, from the poorest in the Bay of Bengal to the wealthiest in the Chesapeake Bay. Dr. Colwell served as the 11th Director of the National Science Foundation and is the 2010 recipient of the prestigious Stockholm Water Prize.
