About

Dr. Sarah Hobbie is a Distinguished McKnight University Professor at the University of Minnesota Twin Cities, USA. Her research focuses on soil carbon dynamics, nitrogen deposition, and the ecological consequences of tree diversity in forest ecosystems. Recent publications highlight her work on soil respiration, the effects of long-term fertilization, and the role of species interactions in relation to climate change.
