George H. Shaw, an associate professor in the geology and geophysics department at the University of Minnesota, is the 1981–1982 AGU Congressional Science Fellow. The fifth person to be selected for the program, he recently began his 1-year term on Capitol Hill.
Rock and mineral physics (including physical properties of minerals under high pressure, phase relations, and polymorphism) are Shaw's main research interests. His most recent research includes studies on the elastic properties of polymorphic materials under high pressure and moderate temperature, elastic behavior in solid-solid equilibrium systems, extrapolation of elastic properties of mixtures at high pressure, the equation of state of alkali metal liquids, and calculations on the energy of planetary core formations. He is also interested in the hydrology of karst terrains and the impact of human activity on groundwater quality in such areas.
