Educational Background

  • Ph.D., 1985, University of California at Los Angeles (UCLA)
  • Diplom-Chemiker, 1979, Technische Universität Braunschweig, Germany

Research Interests  (click on red links for additional information)

  • Organic geochemical research funded by the Department of Energy: Stable isotopes in fossil fuels (oil, coal, gas) reveal how original biological material, heat and time affected the chemical composition of sedimentary organic matter.
  • Paleoceanographic research funded by the National Science Foundation: Paleoclimatology of laminated sediments from the Santa Barbara Basin off California of the last 2,000 years.
  • Stable isotopes in ecology.
  • Development of novel hydrogen, carbon, nitrogen and oxygen stable isotope reference materials (http://mypage.iu.edu/~aschimme/hc.html).

Courses Taught

      Isotope systematics and graduate seminars

Current Graduate Student Projects

  • Ling Gao: Hydrogen stable isotopes in sedimentary organic matter and natural gas
  • Katarina Topalov: Stable isotopes in bone collagen and other fossil biogenic materials (see bone collagen poster)
  • Agnieszka Furmann: Microbial methane in coal

Current Funding

  • Significance of isotopically labile organic hydrogen in the thermal
    maturation of source rocks (DOE, Basic Energy Sciences)
  • Collaborative research: Hydrogen isotopic studies of marine dissolved
    and particulate organic matter (NSF, OCE, Chemical Oceanography)
