Research Interests: Currently my research focuses on understanding past marine responses during both climatically dynamic intervals lasting over a million years in duration (long-lived) and those spanning less than 200 thousand years in duration (short-lived). The first project utilizes drilled marine sediment samples from the International Ocean Drilling Program (IODP) Expedition 342 Site U1409, offshore Newfoundland. This project aims to interpret marine productivity through long-term trends and short-lived warming events that punctuate it during the early-middle Eocene Epoch, beginning about 56 million years ago (Ma). The second project utilizes drilled marine sediment samples from the International Ocean Discovery Program (IODP) Expedition 371 Site U1509, southern portion of the New Caledonia Trough. This project aims to interpret ocean circulation during the Paleocene Epoch (about 65 to 56 Ma) when continents were configured differently than today and the Antarctic Circumpolar Current was not fully formed.
