Warren joined the faculty at Princeton University after completing a junior research fellowship at the University of Oxford.[2] From 2014 until 2017, she held the university's Philip and Beulah Rollins Preceptorship in the Department of History.[3] In her final year of the preceptorship, she published New England Bound: Slavery and Colonization in Early America through Boni & Liveright.[4] The idea for the book came to her as a doctoral student at Yale, when she came across a 17th century account of the rape of a New England slave.[5] It won the 2017 Merle Curti Award as the best book published in American social history and was a finalist for the Pulitzer Prize for History.[6]
