报告人简介：

Timothy R. Filley is professor of Geochemistry, Department of Earth, Atmosphere and Planetary Sciences, Purdue University. His research interests are factors controlling stabilization/destabilization of soil organic matter, terrestrial isotope ecology, microbial decay of natural products and emerging pollutants, invertebrate impacts on soils, decomposition chemistry of manufactured carbonaceous nanomaterials. His group use field-based experiments, such as the Free Air CO₂ Enrichment (FACE) sites, chronosequences of forest encroachment, laboratory mesocosm experiments and a variety of analytical approaches including analysis plant and microbial organic chemistry (e.g. lignin, carbohydrates, amino compounds), microbial activity assays, and stable isotope techniques (e.g. compound specific stable isotope analysis) to investigate these processes.
