I am a Distinguished Professor Emeritus in the Bren School of Environmental Science & Management at the University of California, Santa Barbara, where I have taught since 1974. I founded the Bren School in 1994 and served as its first dean for six years. In my research, I study snow hydrology, Earth system science, remote sensing, and information systems. From 1990-1992, I was the senior project scientist for NASA’s Earth Observing System when the configuration for the system was established and instruments like MODIS were designed. My current work focuses on snow, water, and ice in the Sierra Nevada and High Mountain Asia, where more than a billion people depend on snowmelt for their water resources, and where the austere surface infrastructure requires that most of the analyses come from remotely sensed data. My study of the optical properties of snow let me help Disney Animation Studios win a 2014 Academy Award for Best Animated Feature Film, Frozen
. A long-time backcountry skier, mountaineer, and rock climber, I led six expeditions to the Hindu Kush range in Afghanistan and have a dozen first ascents there, hence my interest in the world’s mountains. I am a Fellow of the American Association for the Advancement of Science and the American Geophysical Union.
