Hello! I am a postdoc at the University of California, Santa Cruz, working in Prof. Christina Ravelo's Paleoceanography Lab. I investigate the long-term evolution of ocean circulation and ice sheet dynamics across orbital to millennial timescales.
My NSF postdoc fellowship is focused on reconstructing North Atlantic ocean circulation and iceberg discharge variability during the early Pleistocene, drawing on core material from International Ocean Discovery Program (IODP) Expedition 395, on which I sailed as a sedimentologist in 2023.
I received my Ph.D. from Columbia University in 2026, where my dissertation examined the evolution of the Antarctic Ice Sheet over the Plio-Pleistocene using IODP Expedition 382 cores from Antarctica's "Iceberg Alley."
I completed my B.S. in Environmental Geosciences (major) and Economics (minor) at Boston College in 2018. In my free time, I enjoy running, cooking, and photography.
