Expertise: Tectonics and Structural Geology, Thermo-/Geochronology, Petrology, and Geochemistry.
I am interested in crustal and lithospheric dynamics and how they affect our environment and planet. I like to combine field-based geological, structural, and petrological observations with geo-/thermo- chonometric and geochemical analyses to elucidate the fundamental processes that drive the tectonics that have and continue to shape our world and resources. I am interested in a range of problems from extensional to contractional tectonics and their influence on geology and geochemistry. I am also deeply interested in the application of geological techniques to other bodies in the solar system.
I currently am working on a field-based research project looking at how critical low-angle normal faulting in the Aegean back arc is to exhumation of high-pressure metamorphic rocks in a metamorphic core complex and the structural dynamics associated with Miocene extension in Greece. Focused on the islands of Andros and Tinos, this research is based on macro- and micro-structural analysis of brittle and ductile structures in metamorphic rocks and discovering the spatio-temporal evolution of those structures with geo-/thermo-chronological dating and geochemistry. I am using detrital zircon U-Pb dating on LA-ICP-MS, in situ U-Pb dating of zircon on SIMS, and zircon and apatite (U-Th)/He low-temperature thermochronology.

-Performed four-week field research, gathered data and rock samples of rocks and mapped geological features using GPS, and Brunton compass -Presented poster at GSA 2009: An Investigation of Geologic Hazards of the North Anatolian Shear Zone near Amasya, Turkey. Presently examine data and samples with Scanning Electron Microscope for interpretation, creating maps for journal articles, interpretation for thesis -Undergraduate Honors Research of Sivrihisar This is what prompted my previous thesis and publication.
