American Society of Naturalists

The ASN and the University of Chicago Press are excited to announce that Dr. Troy Day has generously agreed to serve as the next Editor-in-Chief of The American Naturalist, starting in January 2027. Troy is a distinguished mathematical biologist whose work sits at the intersection of evolutionary biology, ecology, and applied mathematics. He is Professor in both the Department of Biology and the Department of Mathematics and Statistics, at Queen's University in Canada. His research spans evolutionary biology, mathematical epidemiology, and the evolutionary theory of infectious disease dynamics, with his group developing mathematical methods—including stochastic processes, dynamical systems, and game theory—to analyze evolutionary and epidemiological questions. He was a Canada Research Chair in Mathematical Biology from 2002 to 2012. He is the author of numerous peer-reviewed articles, two mathematics textbooks, a textbook on mathematical modeling in biology, and a monograph on nongenetic inheritance in evolutionary biology. During the COVID-19 pandemic, he served on the Modeling Consensus Table of the Ontario COVID-19 Science Advisory Table. His publications include about a dozen articles in The American Naturalist. His achievements have been widely recognized. His awards include an E.W.R. Steacie Fellowship and a Canada Council Killam Research Fellowship, and he is an elected Fellow of both the American Association for the Advancement of Science and the Royal Society of Canada. His work on both ecology and evolution, merging theory and data, places him at exactly the intellectual crossroads that The American Naturalist has made its brand. He has the experience as an author, reviewer, Associate Editor, and Co-Editor, to serve in this role effectively. In our past interactions with him, we all felt that he has a history of writing perceptive, kind, and rigorous reviews and decisions. We are confident that his expertise and style of editing will be exactly what the journal needs for the challenging next four years. Dr. Day will be transitioning into his new role over the course of the coming year with the outstanding assistance of outgoing EIC Volker Rudolf and Managing Editor Owen Cook.
