Staci earned her PhD from the Department of Geological Sciences at UT in 2002, working with Jim Connelly and Ian Dalziel on paleogeographic reconstruction of Rodinia, conducting field work in South America and Scotland and using geochemical tools, such as U/Pb geochronology and Sm/Nd and Pb isotope geochemistry. She continued isotopic work as a postdoc at UT, studying the Neoproterozoic Knoydartian Orogeny of Scotland and managing the U/Pb geochronology and radiogenic isotope facilities. In 2004 she took a position as a Research Assistant Professor at the University of North Carolina, Chapel Hill where she taught classes in petrology and isotopes and maintained the U/Pb geochronology and isotope geochemistry facilities. From 2006 to 2011 she was an Assistant Professor at California State University Bakersfield where she taught structural geology, mineralogy, petrology, field methods, tectonics and various general education courses as well as led an NSF-funded education outreach program to empower local teachers in teaching Earth sciences and co-lead a Keck Summer Research Program in the Sierra Nevada with Jade Star Lackey. In 2011 she gave up her tenure track position to return to UT as a radiogenic isotope geochemist and TIMS lab manager. She is responsible for the clean labs of Jay Banner and John Lassiter, and the TIMS lab facility but also works with the multicollector ICP and HR ICP mass spectrometer facilities in the department. She guides students in developing new analytical techniques, conducting their own analyses in all of these labs, and maintaining the facilities. She supervises contract work in the labs and co-teaches a course on mass spectrometry analytical techniques. In her spare time, she has developed collaborations that allow her to continue research in geochemistry, geochronology and paleogeographic reconstruction, train users to use the Departmentís research grade petrographic microscopes, and is an instructor for GeoFORCE.
