ored him with the Albert Einstein World Award in Science. He received his bachelor’s degree in electrical engineering from the Massachusetts Institute of Technology, where he was also a varsity baseball player, and both his master’s and doctoral degrees from the University of Illinois in electrical engineering, with a minor in physics.

Brent Clothier, Horticultural and Food Research Institute of New Zealand (HortResearch)

Brent Clothier is a soil physicist and environmental scientist who is science leader of the Sustainable Land Use team within HortResearch. In his 30-year research career, he has published more than 165 scientific papers on the movement and fate of water and chemicals in production systems and the environment. He has led projects on risk assessments of land-use practices and the protection of soils, surface water, and groundwater from contamination, both in New Zealand and in the Pacific islands. Clothier is the program leader of New Zealand’s major soil-science research program SLURI (Sustainable Land Use Research Initiative). He has a B.Sc. (Honors) from Canterbury University, and a Ph.D. and D.Sc. in soil science from Massey University. He is a fellow of the Royal Society of New Zealand, the Soil Science Society of America, the American Society of Agronomy, the New Zealand Soil Science Society, and the American Geophysical Union. He received the Don and Betty Kirkham Soil Physics Award from the Soil Science Society of America in 2000.

Susan Trumbore, University of California, Irvine (UCI)

Susan Trumbore is professor of earth system science and director of the UCI branch of the UC Institute for Geophysics and Planetary Physics. She received a B.S. in geology from the University of Delaware and a Ph.D. in geology and geochemistry from Columbia University’s Lamont-Doherty Geological Observatory (1989). After postdoctoral work at the Swiss Federal Institute of Technology and Lawrence Livermore National Laboratory, she joined the Earth system science faculty at UCI as a founding member in 1991. Dr. Trumbore studies how the Earth’s natural exchanges of carbon among ocean, land, and atmosphere are altered by human activity. She uses the distribution of radiocarbon added to the atmosphere in the 1960s during nuclear weapons testing to determine the timescale of carbon exchange between ecosystems (plants and soils) and the atmosphere.
