I am interested in how holocene climate varied in the Southern Hemisphere's mid- to high-latitudes. I use sediment cores from fjords and lakes in Patagonia to reconstruct precipitation, temperature, and wind variability.
My research focuses on the impacts of climate change on phytoplankton in rapidly changing polar marine ecosystems. I combine remote sensing and fieldwork techniques to study phytoplankton and primary production in both the Chukchi Sea (Arctic) and the Amundsen and Ross Sea polynyas (Antarctic). My primary focus is on phytoplankton growth underneath thinning sea ice in the Arctic.
