Assistant Professor Sarah Feakins (Earth Sciences)
Sarah Feakins joined the Department of Earth Sciences in 2008. Her research is focused on reconstructing past climatic and terrestrial environmental change, including the environments in which our species evolved. Her lab work centers on teasing out the climatic, environmental and biological signals contained within organic molecules, specifically the waxy coating on plant leaves. These leaf waxes are preserved over millions of years in the sediments below lakes and oceans. Understanding how our environment responded to climate change in the past helps to assess our future.
