Climate Change, Glacial Geology, Lake Sedimentology
I am interested in documenting the geologic record of global climate change. My focus is on the timing of fluctuations of mountain glaciers during the last 2 million years in the Andes Mountains of Peru and Ecuador, and on the geologic record of El Nino preserved in lake deposits in the tropics. I have also applied these techniques to lake deposits in the northeastern U.S. These records provide important information on natural cycles of climatic change on which human effects have been superimposed.
