|Jaime D Barnes|
Stable isotope geochemistry, metamorphism and volatile transport in subduction zones, fluid-rock interaction and metasomatism, geochemical cycling, stable chlorine isotopes
|Elizabeth J Catlos|
The geological evolution of the Turkey (various regions), Himalayas (India and Nepal), south India (Tamil Nadu), and Slovakia (Carpathians); models for heat, mass, and fluid flow along tectonic structures; developing techniques for isotopic microanalysis; applying mineral equilibria to estimate environmental conditions during dynamic recrystallization; accessory mineral geochronology; stone decay and deformation mechanisms. Overall, I am interested in developing and applying petrochemical and geochemical techniques to the study of lithosphere dynamics.

|Harm J Van Avendonk|
Van Avendonk is an active-source seismologist who specializes in the acquisition and inversion of seismic refraction data on land and at sea. Often these seismic refraction data are used for a tomographic inversion. The resultant seismic velocity models help us to interpret the composition of the Earth’s crust and mantle, the geometry of sedimentary basins, and the structure of plate boundaries.
