Biography

Bachelor of Arts

Mathematics and Atmospheric and Oceanic Sciences,Ìýsumma cum laude, Â鶹ӰԺ (2019)

Research Interests: Thwaites Glacier, surface mass balance, extreme snowfall events, AntarcticÌýatmospheric rivers

IÌýresearchÌýthe impacts of snowfall and extreme precipitation events on theÌýsurface mass balance ofÌýWest Antarctica, in particular Thwaites Glacier. I examine how large-scale atmospheric circulation over the Southern Ocean, including the coupling of low- and high-pressure systems, helps to drive warm and moist air masses onto the West Antarctic Ice Sheet. On Thwaites Glacier, I study the surface mass balance impacts of extreme snowfall events by looking at observations from automatic weather stations, atmospheric reanalysis, and climate models.ÌýMy research is part of the , TARSAN project.ÌýRecently, I have started looking into the impact ofÌýatmospheric rivers (narrow bands of warm and moist air that travel south from the midlatitudes) onÌýThwaites Glacier and Antarctic precipitation.

In December 2019 I graduated from the University of Colorado with an honors thesis on the Large-Scale Atmospheric Drivers of Snowfall over Thwaites Glacier, Antarctica. I am now a second-year PhD student in the Ice Sheets and Climate group, working with Prof. Jan Lenaerts.Ìý

In my free timeÌýI love bouldering,Ìýhiking,Ìýskiing, and cooking.Ìý
