I direct the SALT Lab in the Department of Psychology and the Department of Mathematics and Statistics at Queen's University, and I am a Fellow in Evolution and Governance at One Earth Future, a "think and do" tank in Colorado. I also sit on the editorial boards of Evolution and Human Behavior, Archives of Sexual Behavior, and Frontiers in Psychology (Social Psychology section).
I study the evolution of cooperation and conflict, mainly in humans. To do this, I develop theoretical models of social evolution and apply them to human psychology. I use both laboratory and real-world data to test hypotheses about social behavior. I earned my Ph.D. in Psychology, Neuroscience, and Behaviour at McMaster University, and held postdoctoral fellowships in Psychology and in Mathematics and Statistics. My work has been published in well-regarded scholarly journals, such as The American Naturalist, Evolution and Human Behavior, Journal of Evolutionary Biology, Proceedings of the Royal Society B: Biological Sciences, and Trends in Ecology & Evolution.
