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)
- Geochemical research on shale gas 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.
- Paleoclimatology of laminated sediments from the Santa Barbara Basin off California.
- Stable isotopes in ecology and environmental sciences, e.g. about the isotopic fate of degrading oil in coastal environments that were effected by the 2010 BP oil spill.
- Development of novel hydrogen, carbon, nitrogen and oxygen stable isotope reference materials, partially funded by the National Science Foundation (http://mypage.iu.edu/~aschimme/hc.html).
