Description of Research |
|
Summary Statement of Research Interests |
|
| I use biogeochemical analytical approaches to answer intriguing questions about climatic and ecological change. Organic geochemical and compound-specific isotopic approaches provide new tools for high resolution studies. Current projects include compound-specific carbon isotopic reconstruction of paleovegetation and development and application of hydrogen isotopic proxies for paleohydrology. | |
Research Specialties |
|
| Compound-specific hydrogen and carbon isotopic analysis; Paleoclimate, Paleoenvironment, Paleoecology; Isotope Biogeochemistry; Organic Geochemistry. | |
