Broadly, I am interested in understanding how the world has changed through time using an integrated Earth systems science approach. For my M.S. research and my current PhD research, I have measured stable isotopes (d13C and d15N) in proteinaceous deep-sea corals from the Monterey Bay, California and the Southeastern United States. These isotopes are proxies for changing ocean surface conditions, such as changes in nutrient input. My PhD research involves using Leiopathes (black coral) from the Southeastern United States to establish records of nutrient and exported POM variability in this region over the last two millennia. I use D14C for dating these corals and I’ll utilize compound specific isotope amino acid analysis (CSIA) to isolate which environmental factors influence the stable isotope records in these corals.
