Tom Hobbs is Head of the Department of Forest, Rangeland, and Watershed Stewardship at Colorado State University. His broad academic interests include the roles of large herbivores in ecosystems. Virtually all of his work links ecological modeling to empirical studies in the field and laboratory. Dr. Hobbs earned his MS and Ph.D. in Wildlife Biology at Colorado State University. He has served NEON as Chair of the Fundamental Sentinel Unit tiger team. The group focused on the observations of responses of biodiversity and ecosystems to climate and environmental change. The team worked to understand the uncertainty associated with each data product generated by an FSU measurement, to generate the data products, and to sketch the algorithms needed to produce them.
