Dr. Vincent Isakson is a former Post-doctoral Research Associate and Ph.D. graduate of the Department of Geosciences at Boise State. His research has focused on high-resolution chronostratigraphic frameworks for Neoproterozoic to Cambrian sequences of the North American Cordillera, including Cryogenian glacial episodes. as well as precise radioisotopic age constraints on Cretaceous global ocean anoxia events.
Dr. Isakson recently joined the faculty of Science, Technology, Engineering and Math at North Arkansas College.
Dr. Tiffany Rivera completed her tenure as a Post-doctoral Research Associate in the IGL in August 2014, and has joined the faculty at Westminster College in Salt Lake City, Utah, where she will continue her studies of the dynamics of magma storage and differentiation at Yellowstone caldera.
Dr. Rivera earned her B.A. in Geology from George Mason University, an M.S. in Geology from Boise State University, and the Ph.D. in Geochemistry from Roskilde University in Denmark, as a member of the GTSNext Marie Curie Initial Training Network of the 7th Research Framework Programme of the European Science Foundation. During her dissertation Tiffany studied the detailed timing of Quaternary geomagnetic field excursions and reversals via integrated 40Ar/39Ar geochronology and cyclostratigraphy of key Quaternary tephra and tektite horizons, as well as the fundamental integration and harmonization of the U-Pb, K-Ar and astronomical dating systems.
Amanda Laib recently defended her M.S. Geology thesis in the Department of Geosciences. Amanda studied the geochemistry, thermodynamics and evolution of high silica magmatic systems including the Miocene Rattlesnake Tuff and the Oligocene Picture Gorge Ignimbrite of central Oregon, via zircon chemistry and geochronology. She is currently a Surface Water Hydrologist with the Idaho Department of Environmental Quality.
Joshua Ekhoff recently defended his M.S. Geology thesis in the Department of Geosciences, presenting a combination of field mapping, structural analysis, soil sampling, geophysics and geochronology to establish the character of ore mineralization in Cretaceous-Tertiary basement rocks near Horseshoe Bend, ID. He is currently a Geological Consultant with Brown & Caldwell in Boise, ID.
M.S. Geology, 2013: Emerald Shirley completed her M.S. Geology degree in late 2013, with a thesis that explored LA-ICPMS U-Pb geochronology, trace elements and Hf isotopes in zircon to establish the origin and evolution of crustal xenoliths from the Eastern and Central Snake River Plain. Emerald is currently a geologist for the Oregon Department of Transportation, in the unstable slopes and material source programs.
Ph.D. Geosciences, 2013: Rimma Khodjanyazova defended her Ph.D. in 2013 on the fusulinid biostratigraphy and Sr isotope chemostratigraphy of Perm0-Carboniferous sections in the Donets basin of the Ukraine, and the Great Basin of the western U.S.A. Rimma used the Isotope Geology Laboratory to collect high-precision Sr isotope ratios on single conodont elements from these sections, as well as in the stratotype sections of the southern Urals, in order to construct an accurate seawater Sr isotope curve for the Late Pennsylvanian-Early Permian, and correlate these basins at high resolution. Rimma is working as an independent consultant.
M.S. Geology, 2012: Bryant Ware defended his M.S. Geology thesis in 2012, which used a combination of structural analysis and both LA-ICPMS and CA-TIMS U-Pb geochronology to analyze the structure and evolution of the Weatherby basin between the Baker and Olds Ferry accreted terranes of the Blue Mountains Province of the northern U.S. Cordillera. Bryant recently completed his Ph.D. at the University of Western Australia in noble gas and radiogenic isotope geochemistry, and is currently a postdoctoral fellow at UWA.
Ph.D. Geosciences, 2010: Gene defended his Ph.D. in 2010 on the application of Sr, Nd, and Pb tracer isotopes, as well as high precision U-Pb zircon geochronology, to understanding the tectonic, structural, and magmatic evolution of ancient island arc systems, with a particular emphasis on the Mesozoic accreted arcs of the northern U.S. Cordilla. Gene is now a project geologist with Barrick Gold Corporation.
M.S. Geology 2010: Chronostratigraphy and isotope geochemistry of late Triassic – Jurassic volcano-sedimentary deposits of the Huntington and Weatherby Formations of the Olds Ferry and Izee terranes of the Blue Mountains Province, northern U.S. Cordillera. Kyle used high precision U-Pb zircon geochronology and Sr-Nd isotopes to constrain the timing and tempo of volcanism, deposition, uplift and deformation in the Olds Ferry terrane and its relationship to onlapping sediments of the Izee basin. He has worked as a geologist and rock analysis engineer, and is currently an environmental scientist at the New Mexico Environment Department-Air Quality Bureau.
M.S. Geology 2008: Western Snake River Plain basalt volcanism. Tiffany analyzed the major, trace and Sr-Nd-Pb isotope geochemistry of a suite of recent monogenetic basalt volcanoes to understand the petrological and tectonic drivers for a marked transition from tholeiitic to mildly akaline basalt eruptions approximately two million years ago. She went on to complete her Ph.D. in 2013 with the Earthtime-Europe GTSNext Initiative, working at the QUAD-lab, Roskilde University, Denmark on the timing of Quaternary geomagnetic polarity excursions and reversals. After a postdoctoral fellowship back at Boise State, she joined the faculty at Westminster College in Salt Lake City, UT.
M.S. Geology, 2007: Geochronology of the House Mountain Gneisses, southwestern Idaho. Now working with U.S. Forest Service, McCall, ID.
M.S. Geology, 2007: Lyndsey completed her M.S. Geology thesis on the strontium isotope chemostratigraphy of the Late Carboniferous – Early Permian, southern Uralian foredeep, Russia-Kazakhstan. She now works as a Project Geologist with Farallon Consulting in Bellingham, WA.
B.S. Geology senior thesis, 2005: Petrology and geochemistry of a diamondiferous eclogite from the Roberts Victor kimberlite, South Africa. Ben completed his M.S. in Hydrology from the University of Texas at Austin in 2008, and a Ph.D. at the Massachusetts Institute of Technology – Woods Hole Oceanographic Institution Joint Program in 2016, and is now a hydrologist at the United States Geological Survey New Mexico Water Science Center.
B.S. Geology senior thesis, 2005: Infrared spectroscopy of nitrogen abundance and aggregation in diamonds from the Star kimberlite, South Africa. Now a high school teacher, Middleton, ID.
