RESEARCH

Most of my research focuses on the Cretaceous – Paleogene (K-Pg) mass extinction. I’m particularly interested in potential climate induced biotic effects around the boundary and why some organisms survived and others perished. Geochemistry, particularly stable isotope analysis of carbonates, is a useful tool for reconstructing the paleotemperatures of past environments and the paleoecology of extinct organisms. I am currently working in several field areas that preserve sediments and fossils from this interval.

Much of my research is facilitated by the Alabama Stable Isotope Laboratory (ASIL).
