About Me

High-latitude Processes: from the Air and Sea.

I study how the Atmosphere and Ocean drive changes in the Ice Sheets, using a combination of unique observations and models.

Broadly, my research involves climate processes at high-latitudes. I’m interested in the interactions between Earth system components in BOTH polar regions. My current research is focused on ice-ocean interaction in Greenland and Antarctica. Are warming ocean waters responsible for the increase in mass loss of marine-terminating glaciers worldwide? How stable are the Ice Shelves, especially the Ross Ice Shelve, which holds back multiple meters of sea level rise locked up in West Antarctic ice? What drives the newly-observed surface melt in the frigid Southern Continent?
