I am a PhD Candidate advised by Dr. Donna Surge studying stable isotope geochemistry and paleoclimate proxy development in bivalves and gastropods. Current research includes the calibration of biogeochemical proxies in freshwater and estuarine bivalves from the Neuse River and its estuary, North Carolina.
