Biography

John Battles is a Professor in the Department of Environmental Science, Policy, and Management at the University of California, Berkeley. His research program focuses on understanding how forests change over time and the complexities associated with these changes. His work emphasizes robust, quantitative field studies as a core methodology, addressing the influence of human activities such as pollution and land transformations on forest ecosystems. Battles investigates the challenges posed by anthropogenic changes and aims to anticipate how forest systems respond to these stressors by studying the dynamics of disturbance and recovery cycles in forest ecology. He is particularly interested in the role of disturbance regimes as predictable aspects of forest dynamics, and he recognizes the need to reassess how ordinary natural processes interact with extraordinary human influences.
