Julie Brigham-Grette was first inspired by Larry Taylor to study glacial geology and paleoclimates during an undergraduate Pleistocene course at Albion College back in the mid-1970s. Field trips to bluff exposures of interstratified tills and lacustrine deposits along Lake Michigan secured her fate as a Quaternary stratigrapher. She began her graduate career in 1977 at the University of Colorado's Institute for Arctic and Alpine Research by studying the glacial and sea-level record of an area of the Cumberland Peninsula, on Baffin Island in the eastern Canadian Arctic under John T. Andrews. This Master's research led to a Ph.D. project funded through the U. S. Geological Survey on the Plio-Pleistocene sea-level history of the Alaskan Arctic Coastal Plain under the supervision of Gifford Miller (CU) and David Hopkins (USGS). Both of these projects incorporated the use of amino acid geochronology -- a relative-age dating method and paleo-thermometer that allows correlation of regional stratigraphic sections. Here at the University of Massachusetts, she and William D. McCoy jointly maintain the Amino Acid Geochronology Laboratory housed in Morrill Science Building and is a part of the UMass Quaternary Program. After post-doctoral work at the University of Bergen, Norway and the University of Alberta, Canada, Brigham-Grette joined the faculty at the University of Massachusetts in the Fall of 1987. Her current interests are directed toward: Revising and modernizing the glacial and sea-level history of the Bering Strait region, the paleogeography of Beringia, and the paleoclimatic history of the Arctic and Subarctic regions. Recent work has involved collaborative projects with Russian geologists in northeastern Russia. Investigations into the late Pleistocene paleoclimatic history and drainage record of Glacial Lake Hitchcock and the Holocene evolution of the Connecticut River. Understanding the climate evolution of the Arctic via a long continuous lake record from El'gygytgyn Crater Lake in northeastern Siberia. Brigham-Grette also supervises students working on hydrogeology and marine studies.
