Broadly speaking, my research involves the interaction of ice sheets, oceans and the climate system on orbital to centennial time-scales. I currently have projects working on the Laurentide, Antarctic and Greenland ice sheets addressing the behavior of these ice sheets and their effects on climate over multiple glacial cycles. I am also beginning work into documenting the natural volatility of the Arctic cryosphere outside of the Greenland ice sheet. My approach to research uses a combination of dating methods (cosmogenic dating, radiocarbon), analytical techniques (isotope and trace element analysis, geochemistry), field geology, and conceptual and analytical models. I believe a holistic approach is required to place data into the global picture and vice versa for the applicability of models.
I am the lead of the PAGES working group, PALeo constraints on SEA-level rise (PALSEA2)
I am part of the larger Quaternary Paleoclimate research group here in CEOAS (website)
Investigating glacial-interglacial and long-term changes in the Greenland, Antarctic and Laurentide ice sheets across the late Cenozoic.
Determining the volatility of Greenland and other Arctic (Svalbard, Alasaka) ice masses in the late Holocene.
And the long-term goal of documenting the last deglaciation of the Laurentide ice sheet and its impacts on the globe.
