Claire Ostwald is a Ph.D. candidate in the Department of Geosciences and a research assistant in the IGL. Claire’s research interests lie in fields of isotope geochemistry and high-precision geochronology, particular for enhancing our understanding of orogenic processes. Her dissertation work will include foundational studies in the application of tandem in situ LA-ICPMS U-Pb and trace element analysis and high precision CA-TIMS U-Pb zircon geochronology.
Mike Mohr is a PhD candidate in the Department of Geosciences and a research assistant in the IGL. Mike’s research focus is in high-precision U-Pb and Th-Pb geochronology for applications in petrochronology, mineral resources, and the geologic time scale. Although he loves zircon (a requirement for geochronologists), he is particularly interested in non-conventional accessory minerals like titanite, chevkinite, allanite, and thorite, and in furthering the utility of Th-Pb dating via ID-TIMS. Mike’s research in Th-Pb geochronology is supported by the Geological Society of America and the Boise State University Nuclear Materials Fellowship.
Travis Leach is pursuing his B.S. Geosciences degree in the Department of Geosciences as a participant in the Ronald E. McNair Postbaccalaureate Achievement Program. Travis’s research in the IGL is focused on the record of ultra-high temperature metamorphism preserved in unique zircon-rutile intergrowths in granulite xenoliths from southern Africa. He is applying a variety of imaging methods with both in situ and isotope dilution geochemical and geochronology analyses to establish the time-temperature evolution of these samples.
Melissa Hill is a M.S. Geology student in the Department of Geosciences, using zircon cathodoluminesence imaging, LA-ICPMS U-Pb geochronology and trace element analysis, Ti-in-zircon thermometry, and CA-TIMS U-Pb geochronology to establish the origins of the crystal load in voluminous high-temperature rhyolites from the Mount Bennett Hills of the Central Snake River Plain.
