Andrea Dutton, a 2019 MacArthur Fellow,[1] is a Professor of Geology in the Department of Geoscience at the University of Wisconsin–Madison where she studies paleoclimate, sedimentology, carbonate geochemistry, and paleo-oceanography.

Following her time at Amherst, Dutton taught 3rd, 6th, 10th, 11th and 12th grade science at Saint Ann's School in Brooklyn Heights, New York City.

[3] During her time as a Research Fellow at ANU, Dutton worked in collaboration with Kurt Lambeck, a geophysicist, to develop an interdisciplinary approach to reconstructing past sea levels using radiometrically dated fossilized coral.

Specifically, Dutton utilizes fossilized coral and limestone rocks to understand how past sea level increased during warming climates throughout earth's history.

By studying an entire reef including the assemblages, algae, and other aspects that inform how the coral grew, Dutton and other researchers can provide a holistic comprehension of sea level.

[5] In her research, Dutton uses chemistry techniques to find the age of the coral and combines this information with the elevational changes of the reef through time to understand sea level changes.

[4] One of her research objectives is to determine when the West Antarctic ice sheet collapsed in the past to help us understand when and how this may occur in the future.
