Arthur is an assistant 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 received graduate training in environmental management at Yale University, and in ecology at the University of Wyoming. He returned to Yale as a postdoctoral fellow, then an associate research scientist. Arthur joined the Department of Environmental Science, Policy, and Management at UC Berkeley in 2016. He also currently serves as a Trustee of the Buffalo Bill Center of the West. When he’s not in the lab, Arthur is with his wife Anna, daughters June and Eve, and dogs Jack and Lupine. In summers, they relocate to Cody, Wyoming, where the Middleton lab has a 'home away from home' at the Center of the West.
