Quaternary Paleoclimate, Glacial Geology
Broadly speaking, my research involves the interaction of ice sheets, oceans and the climate system on orbital to centennial time-scales. I am interested in the effects of deglaciation on climate, constructing paleoclimate records, and the role of the ocean in modulating the climate response between hemispheres. I currently have projects working on the Laurentide and Greenland Ice Sheets addressing the behavior of these ice sheets and their effects on climate over multiple glacial cycles. 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. Here are links to my Research Group Website and my Publications.
I am looking for students interested in completing a Ph.D. for admission in the Fall of 2013; please contact me if interested. NOTE THAT I HAVE MOVED TO OREGON STATE UNIVERSITY NOW as an Associate Professor in the College of Earth, Ocean, Atmospheric Sciences (CEOAS). My new webpage is linked here.
