Stephen J. Pyne is a Senior Sustainability Scientist, Global Institute of Sustainability, and Regents' Professor, School of Life Sciences, at Arizona State University. An author and world-renowned expert on exploration and the history, ecology, and management of fire, Dr. Pyne's research interests focus on how people and nature interact. In his own words: "It all began when, a few days after high school, 18 years old, I joined the forest fire crew at the North Rim of Grand Canyon. I returned for 15 seasons. Everything I've written, even the fact I write at all, dates from those years on the Rim."
