Research Interests


Currently my research efforts are focused upon unraveling the polyphase mid-Paleozoic deformational pulses that assembled the crystalline metamorphic terranes  exposed in the southernmost Appalachians of Alabama and Georgia. In addition to detailed mapping and structural analysis, I am conducting a regional geothermometry and geobarometry study from samples collected in amphibolite facies metamorphic rocks, primarily Neoproterozoic garnet-bearing schist, gneisses, and quartzites units mapped in the eastern Blue Ridge belt. Several transverse megascopic fold structures within the research area expose significant structural relief, and are the subject of current structural and geothermobarometric analysis. These studies will attempt to correlate isothermal and isobaric surfaces with deformation produced from Alleghenian structures- indicating that the present geometry is not solely inherited from the original Acadian dynamothermal event. Microprobe analyses are ongoing at the microprobe facility at the SOMED facility, University of Alabama, Tuscaloosa. Additional ongoing research includes the application of GIS and CAD to the solution of geoscience problems, and the application of high resolution GPS technology to the earth sciences.
