She graduated from Tatnall High School in 1981 and then graduated summa cum laude in Earth Sciences from Dartmouth College in 1985 with her thesis Magmatic Garnets from the Cardigan Pluton, New Hampshire. She received her Doctor of Philosophy in Geosciences with distinction in 1993 from, Lamont-Doherty Earth Observatory with her thesis Mantle Melting and Crustal Recycling at Subduction Zones.
She was a post-doctoral fellow at Cornell University from 1993 to 1995.
She had various faculty positions at the University of Kansas and Boston University. In 2008, she moved to Columbia University.
She is a 2012 MacArthur Fellow. She has spent her career researching magma and volcanoes. One specific area of her research is how the chemical composition of magma and crystals that form during eruption can provide information about the amount of water present during the eruption and explain how explosive it was.
She has done field work around the ring of fire, Philippines, Nicaragua, Iceland, and across the southwest United States as well as the Aleutian Islands.
