Todd Rosenstiel will serve as the next dean of the College of Liberal Arts and Sciences, effective Sept. 1. He joined the biology faculty at Portland State as an assistant professor in 2006. He has served as the director of the Center for Life in Extreme Environments (2014-2018) and Associate Dean of Research and Graduate Studies (2016-2020).
An internationally recognized plant biologist, his current research primarily focuses on the interactions between trees, atmospheric chemistry, human health, and climate change. In addition, his laboratory research group examines the ecology and physiology of plants that live in extreme environments, including the fundamental role of mosses in shaping the future of a warming Antarctica. Throughout his career, he has been a strong advocate for building collaborative multidisciplinary research teams and advancing opportunities for involving undergraduates in impactful research at PSU.
Rosenstiel received his B.S. in biology from Northland College in Ashland, Wisconsin, and his Ph.D. in ecology and evolution from the University of Colorado, Boulder. Before joining PSU, he was a postdoctoral fellow at the Cooperative Institute for Research in Environmental Sciences at the University of Colorado, Boulder.
