As an historian of the biological sciences in the 19th and 20th centuries, I teach courses on science and religion, the history of evolution theory, and the history of medicine. My research focuses on the history of the naturalist tradition (evolutionary biology, ecology, conservation biology, etc.) in the twentieth century.
