Julie Brigham-Grette
Julie Brigham-Grette (born January 11, 1955 in Albion , Michigan ) is an American Quaternary geologist. She is a professor at the University of Massachusetts Amherst .
Brigham-Grette studied geology at Albion College in Michigan with a bachelor's degree magna cum laude in 1976 and at the University of Colorado with a master's degree in 1980 on the Quaternary of Baffin Island and a doctorate in 1985 with GH Miller and DM Hopkins on a subject on Quaternary geology in the Arctic of Alaska . In 1983/84 she conducted research at the University of Bergen and from 1985 to 1987 as a post-doctoral student at the University of Alberta and the Geological Survey of Canada. In 1987 she became Assistant Professor , 1993 Associate Professor and 2001 Professor of Earth Sciences at the University of Massachusetts at Amherst . From 1998 to 2000 and from 2001 to 2004 she was Deputy Head of the Faculty and Acting Department Head in between .
She is engaged in palaeoclimatological, glaciological and geological studies of the Quaternary in the Arctic, including research in Canada, Alaska, Siberia and Svalbard , with a focus on the area on both sides of the Bering Strait. From 2007 onwards, she was significantly involved on the US side in the joint project with European ( Martin Melles ) and Russian scientists to evaluate sediment drill cores from Lake Elgygytgyn in Northeast Siberia, which provided a precise overview of the climate history of the past 3.6 million years in the Arctic. This resulted in new knowledge about climatic fluctuations in the interglacial periods and the existence of so-called super warm periods (see article by Martin Melles).
In 2002 she used the icebreaker of the US Coast Guard Healy to extract drill cores from the Bering and Chukchi Seas .
In 2002 she became a Fellow of the Geological Society of America . She was Chair of the American Quaternary Association from 2000 to 2004 and Chair of the American Geophysical Union's Paleoclimatology and Paleo-Oceanography Division from 2010 to 2012 .
She has been married to Roger O. Grette since 1983 and has two sons.
