Geophysics

Tibet SeismicThe geophysics program at the University of Illinois includes mineral physics, seismology, geodynamics, and fluid dynamics. Prof.Wang-Ping Chen works on the nature of seismogenesis along the entire depth of subduction/collision zones, as well as on mantle structure, active mountain building, and the rheology of the lithosphere. His research approach involves quantitative analyses of data recorded by various global and regional seismograph networks with tectonic interpretations integrating other geophysical, geodetic, and geologic data. Prof. Xiaodong Song studies the structure and dynamics of the planet‘s interior by studying travel times of seismic waves. Song and his co-workers have monitored the motion of the Earth‘s inner core, resulting in publications that have demonstrated that the Earth‘s inner core rotates faster than its mantle. Jay Bass uses a variety of sophisticated techniques (including diamond anvils, Brillouin Spectroscopy, and the Advanced Photon Source) to characterize mineral phases that exist in the mantle, and to interpret the mantle‘s chemical composition. Prof. Sue Keiffer focuses on studying the behavior of geological fluids in extreme environments (ranging from water in rapids, to vapors in geysers, to debris from meteorite impacts, to ash flows from volcanic eruptions) involving strongly nonlinear effects. Prof. Jonathan Tomkin models glacial erosion and tectonic uplift in active orogens, as well as sediment erosion and transport phenomena.
