I am a Ph.D. student working with Dr. Donna Surge interested in stable isotope geochemistry, paleoceanography, and paleoclimate proxy development in bivalves and gastropods. Current research includes examining elemental ratios as indicators of paleoenvironmental conditions in modern and archaeological limpet shells.
