I am a Professor in the Department of Ecosystem and Conservation Sciences, and Director of the Numerical Terradynamic Simulation Group (NTSG) at the University of Montana. My expertise and interests include understanding climate impacts to vegetation growth and water-carbon-energy connections, emphasizing boreal and Arctic ecosystems. My research is multi-disciplinary, spanning the fields of ecology, hydrology, remote sensing and ecosystem modeling. My scales of interest range from landscape to global extents, emphasizing the use of satellite remote sensing and ecological modeling for environmental assessment and monitoring. I have contributed to more than 150 peer-reviewed scientific publications in my field, which have been cited more than 13,000 times in the literature. My recent projects include: systematic mapping of freshwater habitats for juvenile salmon across all major North Pacific rivers; developing new satellite capabilities for monitoring vegetation drought stress and productivity. I serve on several NASA Earth observation mission science teams working to advance ecological understanding and applications using satellite observations. I am an avid hiker and kayaker, enjoying the wilds of NW Montana with my 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, 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.
