Bio
I am an observational chemical oceanographer with an interest in polar marine biogeochemical cycling, primarily in the Arctic Ocean. I joined Columbia’s Department of Earth and Environmental Sciences/Lamont-Doherty Earth Observatory faculty as an Assistant Professor in January 2026. Prior to this, I was a postdoctoral scholar at the Cooperative Institute for Climate, Ocean, and Ecosystem Studies (CICOES) at the University of Washington (UW) and a Science, Engineering, Enrichment, and Development postdoctoral fellow at the Applied Physics Laboratory (APL-UW). Since completing my PhD in 2020, I have been investigating trace metal cycling in the Arctic Ocean using a combination of traditional trace metal techniques and novel sampling methodology. My current projects combine the biogeochemistry of metals and macronutrients with high-resolution physical measurements (such as volume transport, current velocity, and hydrography) to best understand the flux of trace metals in and out of a rapidly changing Arctic ecosystem.
My current projects are 1) a time series of trace metals (Mn, Fe, Ni, Cu, Zn, Cd, Pb) and macronutrients in the Bering Strait, the sole point of exchange between the Pacific and Arctic oceans, maintained since 2021 (collaboration with APL-UW); 2) tracing and determining the impact of freshwater fluxes on biogeochemistry from the Arctic to the North Atlantic via the Labrador Sea and the East Greenland Current (collaboration with VIMS and UGA-Skidaway); and 3) the effect of freshwater on the Siberian Arctic ecosystem during a period of increased warming and “Atlantification” (NSF-funded partnership with NABOS, collaboration with OSU, WHOI, URI).
