David D. Breshears is a Professor of Natural Resources in the School of Natural Resources and the Environment at the University of Arizona; he also has a joint affiliation with the Department of Ecology and Evolutionary Biology.  His research focuses on the ecohydrology of dryland ecosystems, vegetation gradients spanning grassland to forest, wind- and water-driven sediment transport and erosion, and particularly on drought-induced tree mortality and climate change. Breshears was a lead author for the Forests chapter of the most recent US National Climate Assessment. He has published more than 100 journal articles, and his work has been covered by the New York Times, NPR All Things Considered, and USA Today, among many others. He is a Fellow of the American Association for the Advancement of Science, the Ecological Society of America, the American Geophysical Union, the Aldo Leopold Leadership Program and the Kavli US Frontiers in Science.
