John is a Professor of Biology at William and Mary and was Dean of Graduate Studies and Research from 2012-2013. The major question that has stimulated most of his research is centered on the role of environmental stressors in moderating ecological and evolutionary change—a question of growing importance as anthropogenic stressors on natural populations continue to increase. He started this exploration by exploring the role of environmental developmental stressors on visual communication, mating, competitive, and anti-predatory behaviors in birds and insects. Subsequently, he expanded his research program to include an explicit conservation angle to study how anthropogenic environmental disturbance (e.g. land use change and noise pollution) affects breeding performance and behavioral strategies in song birds. One of his current studies analyzes how the presence of World Bank projects affect bird biodiversity. Before William and Mary, Swaddle was an assistant professor at University of Bristol, where he also received his Ph.D in Behavioral Ecology.
