Sarah Hobbie is a Professor in the Ecology, Evolution and Behavior department at the University of Minnesota. She is an ecosystem ecologist, known for her studies of terrestrial carbon and nutrient cycling in ecosystems ranging from tundra to cities. Hobbie grew up in St. Paul, Minnesota. She graduated from Carleton College in 1986 with a degree in biology and earned her PhD in 1995 from the University of California, Berkeley. After her PhD, she was a post-doctoral fellow at Stanford University. In 1998, she joined the faculty at the University of Minnesota, where she is a Resident Fellow of the University of Minnesota’s Institute on the Environment and is involved in undergraduate writing across the curriculum programming and in graduate education leadership.

Research Interests

Hobbie's research addresses the influence of human activities on terrestrial ecosystems. She explores the influence of human-caused changes to the global and local environment - rising atmospheric carbon dioxide, increased atmospheric nitrogen deposition, climate change, urbanization, and plant species compositional shifts - on ecosystem processes, particularly terrestrial carbon and nutrient cycling and the flow of nutrients from land to water. She is active in the National Science Foundation's Long Term Ecological Research program (LTER), with ongoing research at the Cedar Creek LTER site in central Minnesota.
