Andrea Graham is a professor of Ecology and Evolutionary Biology at Princeton University and the former co-Director in the Program in Global Health Immunity and Disease Ecology from 2015 to 2022. Her research focuses on the interplay between hosts, parasites and disease and seeks to understand how natural selection has shaped strategies for both host defense and parasite transmission. Her lab, the Graham Group, draws on the concepts and theories of evolutionary ecology to understand how immune system behavior emerges from the action of individual cells with a particular emphasis on T cells and neutrophils.
