Research and graduate education in the Department of Earth Sciences focuses on the following subfields: (a) Geophysics: tectonics, seismology, remote sensing, and fault mechanics, as well as earthquake hazards; (b) Volcanology: geochemistry, physical volcanology, igneous petrology, and volcanic systems modeling; (c) Climate science: glaciology, paleoclimate and glacial modeling, oceanography, and ice physics; (d) Paleontology: vertebrate paleontology, paleoecology, paleobiogeography, and phylogenetics; (e) Surface processes: Geochemical modeling, hydrology, soil and aqueous geochemistry, landslides, sedimentology and stratigraphy, geomorphology, and fluid mechanics; (f) Planetary Geology: space physics, astrobiology, and planetary interiors. Positions are limited duration teaching appointments that typically do not exceed one year; there may be a possibility of renewal up to a total of three years, depending on program needs, funding, and performanceDepartment: CAS Earth Sciences.
