Arthur is an associate professor of wildlife management and policy. He leads a variety of interdisciplinary research efforts on wide-ranging wildlife and large-landscape conservation, and works actively to ensure positive outcomes of this work for communities. Arthur's earliest work with wildlife was as a falconer and raptor biologist. He later pursued graduate training in environmental management at Yale University, and in ecology at the University of Wyoming. He returned to Yale as a postdoctoral fellow. Arthur joined the Department of Environmental Science, Policy, and Management at UC Berkeley in 2016. He is currently serving as Senior Advisor for Wildlife Conservation at the U.S. Department of Agriculture. When he’s not in the lab, Arthur is with his wife Anna, his daughters June and Eve, and their dogs Jack and Lupine. In summers, the family relocates to Cody, Wyoming, where the Middleton lab has a "home away from home" at the Center of the West.
