   personal_statement: 'My doctoral research focused on utilizing accessory mineral
     U-Pb ID-TIMS (isotope dilution thermal ionization mass spectrometry) geochronology
     to examine the plausibility of a causal link between large igneous province
     (LIP) magmatism and mass extinction, with particular focus on the end-Permian
     and early-Jurassic extinction events. This work yielded high-precision timelines
     for extinction and LIP magmatism, as well as the ability to resolve their relative
     timing, and lead to a general model predicting the efficacy of magmatism as
     the primary trigger of mass extinction.My current research is focused on application
     of uranium-based geochronometers (U-Pb, U-Th, (U-Th)/He) to date volcanic rocks
     by utilizing TIMS, SIMS (secondary ion mass spectrometry) analysis on accessory
     phase minerals (e.g., zircon, allanite) primarily for the purpose of accurately
     determining the timing of voluminous eruption and for constructing comprehensive
     eruption histories of long-lived volcanic systems characterized by potential
     future volcanic hazard.Ongoing projects include: (1) Leading a group of CalVO
     scientists in an effort to better understand the threat of volcanic hazards
     from the Clearlake Volcanic Field (CLVF). The CLVF is the closest young, long-lived
     volcanic system to the densely populated CA Bay Area. In this project Im employing
     U-Pb zircon surface dating to better constrain the eruption history of the volcanic
     field. (2) Determining the timing of large Pleistocene volcanic eruptions in
     Alaska by zircon surface U-Th-Pb SIMS geochronology. (2) (3) Using zircon U-Pb
     SIMS and TIMS to date the eruption of key Neogene and Quaternary stratigraphic-marker
     volcanic ash beds in western North America for use in regional correlation and
     paleo-climate and paleo-environment reconstruction. (4) Employing zircon and
     allanite U-Th SIMS dating of the Pleistocene record of rhyolite dome extrusion
     at the Coso volcanic field (California) in order to better constrain magma petrogenesis
     and more accurately assess hazard potential. (5) Using zircon U-Pb ID-TIMS dating
     of volcanic ash beds intercalated with the Miocene Columbia River LIP basalt
     flows to investigate eruption tempo at the millennial scale, which informs magma
     generation and climate feedback models.'
