Dr. Ratajeski's teaching responsibilities at UK have included Introductory Environmental Geology (EES 110), Geology of Natural Resources (EES 120), Geology of National Parks (EES 180), Phyiscal Geology (EES 220), Fundamentals of Geology I (EES 230), Fundamentals of Geology II (EES 235), Mineralogy (EES 360), Igneous and Metamorphic Petrology (EES 461), Graduate Seminar (EES 570), and Experiential Education (EXP 396).
Kent Ratajeski’s research interests include: (1) the igneous petrology, geochemistry, and geochronology of granitic rocks, and (2) geoscience education and online curriculum development. His doctoral work in igneous petrology with Allen Glazner at UNC-Chapel Hill involved a study of the Late Cretaceous granites in Yosemite Valley, California which included field mapping, whole-rock and mineral geochemistry (including isotopes), U-Pb zircon geochronology, and partial melting experiments carried out at the USGS in Menlo Park, California. The results of his research imply that large-volumes of granitic magma may be derived by partial melting of mafic lower crust of continental-margin arcs, without the appreciable addition of an ancient crustal component. Kent has been back to the Sierra Nevada several times for collaborations with other researchers. Dr. Ratajeski has advised undergraduate research projects of igneous and metamorphic rocks in Maine and Georgia. More recently, Dr. Ratajeski has applied the hornblende-plagioclase geothermobarometer to constrain depths of emplacement for the Buena Vista Crest, Yosemite Valley, and Sonora Pass intrusive suites in the Sierra Nevada batholith of California.
Kent has also been developing innovative ways to integrate research and education. His postdoc with David Mogk at Montana State University in 2004-2005 resulted in several online educational modules housed at the Science Education Resource Center at Carleton College which use web-based geochemical and crystallographic databases to encourage interactive learning within the mineralogy and petrology curriculum. A member of the International Association for Diversity in Geoscience, his work on making the imagery of introductory geology courses more accessible to students with visual impairments was recently the topic of a poster presentation at a professional conference and the focus of a $5K grant from the American Geophysical Union which resulted in the Geologic Tactile Image Repository. In 2017, he was a recipient of the "Breaking Barriers Award" by UK's Disability Resource Center for his efforts to eliminate barriers to inclusion for disabled students.
