Research

Plants are sensitive recorders of climatic and atmospheric conditions through the stable isotope signature of their tissues. Some plant compounds, such as lipids, are well preserved in the geologic record, and their isotope ratios can tell us a great deal about the growth conditions (paleoecology, climate, atmospheric conditions) of the plants that produced them. However, to decipher these records, we must understand the factors that control these isotope signatures in the modern ecosystems. Therefore, my research focuses on both modern calibration of new isotopic proxies, as well as applications of those proxies to the geologic past during times of ecologic and climatic changes. Examples of past and current research include: Hydrogen Isotope Ratios of Plant Lipids as a Paleohydrologic Proxy, Terrestrial Ecosystem Responses to the Paleocene-Eocene Thermal Maximum, Reconstructing Neogene Grasslands.
