- 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

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)
- Collaborative Research: An ultra-high resolution, multiproxy study of the
past 2,000 years of climate change in Southern California
(NSF, OCE, Marine Geology and Geophysics)
Service
- Indiana Zinc is distributed worldwide for the reduction of water to elemental hydrogen, for off-line determination of the D/H stable isotope ratio. Technical and logistic details are available at http://mypage.iu.edu/~aschimme/zinc.html.
- Stable Isotope Reference Materials for organic hydrogen, carbon, nitrogen, and oxygen are available for on-line and off-line operations; for details see http://mypage.iu.edu/~aschimme/hc.html or email Arndt Schimmelmann.
