Earth’s climate is warming at a pace and magnitude unprecedented in recent times, with profound consequences for terrestrial ecology and hydrology. My research aims to contribute to our understanding of future global change by examining ancient changes in climate, ecology, and the carbon cycle from the Cretaceous to the Holocene by using organic and stable isotope biogeochemical tools.Some of my current research projects are focused on developing new tools to reconstruct changes in terrestrial paleoecology and paleoclimate using fossil chemicals (biomarkers) specific for various plant taxa. These plant-specific biomarkers provide clues to paleoecological change and their carbon and hydrogen isotope ratios provide powerful information on paleoenvironmental conditions.My research field areas include Wyoming, Tennessee, Florida, North and South Carolina, Georgia, California, and Ireland.
