John S. Kimball is a Professor of Systems Ecology at the University of Montana. He received the B.A. and M.A. degrees in Physical Geography at San Diego State University in 1987 and 1990, and the Ph.D. in Bioresource Engineering from Oregon State University in 1995. His research interests include the integration of ecological theory with satellite remote sensing and computer modeling for better understanding terrestrial ecosystem structure and function, from single plot to global scales. Dr. Kimball is a member of the NASA Soil Moisture Active Passive (SMAP) Mission Science Definition Team and EOS MODIS and AMSR-E instrument science teams, and is working towards improved measurement and monitoring of global carbon and water cycles through synergistic use of biophysical process models and satellite remote sensing. He is an avid swimmer, hiker and kayaker and enjoys the wilds of NW Montana with his family.

My expertise and interests include the study of climate impacts to water resources and ecosystems; water, energy and carbon cycle interactions; remote sensing; hydrological and ecosystem process modeling. My research activities integrate ecological theory, field measurements and emerging technologies including satellite optical and microwave remote sensing, geographic information systems, and computer simulation models to describe the function, distribution and condition of vegetation and underlying environmental drivers across the landscape. I emphasize an ecosystem perspective for understanding physical and biological processes and interactions, integrating across disciplines and various scales.
