Research Interests:

My broader interests are in Marine Paleobiology, Paleoecology, Invertebrate Paleontology, and Biogeochemistry. My research questions ultimately center around the relationship between the geochemistry of the shells of extinct cephalopods and their paleoenvironment and paleobiology. I am particularly interested in various applications of carbon and oxygen isotopes to understanding where different morphologies of ammonites lived in the water column, as well as attempting to deconvolve the influence of their biology (metabolic respiration, life history, growth rates) on the isotopes recorded in their shells.

Current Research Projects:

The first chapter of my dissertation is focused on using paleotemperatures from ammonite shell oxygen isotopes from the Western Interior Seaway (WIS) to reconstruct WIS paleoceanography of the Late Cretaceous. Another project in development is looking at isotope variability within and between multi-species fossil assemblages contained within large concretions to compare oxygen isotopes reflecting the different temperatures of their respective environments.
