Training Programs and Courses

  • Graduate Student Assistantships: 2 graduate assistantships per semester (one in Earth & Planetary Sciences and another in Biology) are offered to train graduate students in the daily operation of instrumentation, instrument maintenance, QA/QC protocols and data reduction.
  • Courses: targeted to motivated undergraduates, graduates and postdoctoral researchers interested in learning more about the application of stable isotope analysis in the planetary, life and medical sciences. The laboratory experience will include full access and training on how to operate and maintain isotope ratio mass spectrometers.
    • Stable Isotope Geochemistry (EPS 405): The aim of this course is to provide students with a basic understanding of stable isotope geochemistry, and it’s application in the geosciences. In particular, lectures will focus on applications to paleoclimate reconstruction, metamorphic and igneous petrology, atmospheric science and meteoritics.
    • Elemental Ecology (BIO 402/502): This aim of this course is to provide students with a basic understanding of the application of stable isotope measurements in ecology and environmental science. Lectures will address the theory underlying the application of stable isotopes at natural abundance levels as tracers and integrators of important ecological and environmental processes.
    • Stable Isotope Seminar (ANTH 502, BIOL 402/502, EPS 400): The CSI brown bag seminar is offered as a one credit course in the Anthropology, Biology, and Earth and Planetary Sciences departments.
