My primary research interests involve reconstructing the paleoenvironment and paleobiology of charismatic extinct cephalopods, particularly ammonites. I work predominantly in the Late Cretaceous Western Interior Seaway of North America, using oxygen and carbon isotopes of ammonite shell material to gain insight into their watery world! Past research has utilized light stable isotopes and trace element ratios in numerical models to reconstruct intra-annual growth rate of Pacific corals and how the timing of their growth relates to different aspects of their environment. I enjoy all work using stable isotopes as a tool to understand past life of marine calcifying organisms.
