Jessica Metcalf is an Assistant Professor of Ecology, Evolution and Public Policy, jointly appointed by WWS and EEB. She is particularly interested in the design and support of vaccination programs, with a focus on using existing data to develop locally tailored control strategies that reflect the shifting epidemiological and demographic landscape across the globe. Most of her research is based around rubella and measles, but she also works on a range of other infectious diseases, addressing issues including the evolution of drug resistance, and the challenges of disease elimination. An ecologist and evolutionary biologist by training, demographic analyses form the core of her research. She has served as technical adviser to WHO on the topic of rubella vaccination.
