Earth Planetary Science Seminar – Dr. Alicia Marie Cruz-Uribe “Prospects and challenges for in situ beta decay geochronology by tandem mass spectrometry”.
February 11 @ 8:00 pm - 9:15 pm
The development of tandem mass spectrometers equipped with collision cells has enabled online interference removal for ICP-MS, with special attention paid to beta decay systems used for geochronology (e.g., Rb-Sr, Lu-Hf). Looking toward the future, novel applications of LA-MC-ICP-MS/MS will expand many fields that utilize high precision isotope geochemistry, including geochronology, biology, and nuclear forensics.
Bio: Dr. Alicia Marie Cruz-Uribe is the Edward Sturgis Grew Associate Professor of Petrology and Mineralogy at the University of Maine, USA. She is head of the MAGIC (MicroAnalytical Geochemistry and Isotope Characterization) Laboratory. Her research interests span the fields of solid Earth petrology, geochemistry, and geochronology, and recently she has pursued techniques more broadly within the field of plasma mass spectrometry. Cruz-Uribe is a current Distinguished Lecturer for the Association of Women Geoscientists, is a member of the Editorial Board of Geostandards and Geoanalytical Research, and serves on the Council for the International Association of Geoanalysts.
