Osvaldo Sala joined Arizona State University as a Wrigley Professor in the School of Sustainability in August 2010. As president of the Scientific Committee on Problems of the Environment and a coordinating lead author of the Millennium Ecosystem Assessment, Sala is an international leader in ecological science and global environmental policy.
Sala has explored several topics throughout his career including water controls on carbon and nitrogen dynamics in arid and semi-arid ecosystems, the consequences of changes in biodiversity on the functioning of ecosystems, and the development of biodiversity scenarios for the next 50 years. He is particularly interested in working with scenarios as a way of simplifying, understanding, and communicating the complex relationships that emerge from the study of social-ecological systems. While pursuing all these different questions, he used different tools from direct observations, manipulative field experiments, to simulation modeling. His work encompasses a broad range of scales from the global to specific regions. He has worked in the Patagonian steppe, annual grasslands of California, steppes of Colorado and deserts of Southern Africa and currently he has experiments in the Chihuahuan Desert in New Mexico. His work is reflected in more than 140 peer-reviewed publications and several co-authored books.
Sala has served as editor of Global Change Biology, the president of the Argentinean Society of Ecology, and a member of the governing board of the Ecological Society of America. Osvaldo Sala is an elected member of the American Academy of Arts and Sciences, the Argentinean National Academy of Sciences, and the Argentinean National Academy of Physical and Natural Sciences.
