Research
Structural Geology and Tectonics
My research is focused on investigation of structural and tectonic problems using micro and macro scale techniques. Areas of interest include: Tectonic of Mid-ocean ridge and trench/subduction zone environments and tectono-magmatic processes asscociated with these regions.
Current Research
I am currently exploring the deformation and structural history at Atlantis Massif detachment fault/oceanic core complex (30 N) on the Mid-Atlantic Ridge. The objective of this study is to decipher deformation mechanisms at Atlantis Massif to reveal how the core complex and related detachment fault has evolved through space and time. This study will use macroscopic core description techniques and Scanning Electron Microscope/Electron Backscatter Diffraction techniques to learn about deformation styles within samples collected at Atlantis Massif.Previous Research
I completed an Honors Senior Thesis at the University of Texas at Austin under Dr. Mark Cloos. I investigated the structural history of Marin Headlands in the San Francisco Bay of California. This research focused on constraining the accertion age of the Marin Headlands seamount with uranium/lead detrital zircon geochronology. The exact age of accretion was relatively unconstrained before my study, with a possible accretion age anywhere from 113 Ma to 30 Ma. The study found that the Marin Headlands seamount accreted to the Franciscan accretionary complex at around 100 Ma.
