Meghan Sullivan is the Rev. John A O’Brien Collegiate Associate Professor of Philosophy at Notre Dame. She teaches courses at all levels, including large introductory courses in philosophy of religion and ethics and specialized graduate seminars on metaphysics, philosophical logic, and rationality. Her research tends to focus on philosophical problems concerning time, modality, and religious belief (but rarely all three at once). Sullivan earned a BA (with highest distinction) from the University of Virginia in 2005, double-majoring in Philosophy and Politics. She studied at Virginia as a Jefferson Scholar. From 2005-2007, she studied at Oxford as a Rhodes Scholar, earning a B.Phil in Philosophy. Then from 2007-2011, she completed her PhD in Philosophy at Rutgers. Her 2011 dissertation was on issues in the metaphysics and logic of change—entitled The A-Theory: A Theory. She was awarded tenure at Notre Dame in 2015. Sullivan has published work in many of the leading generalist philosophy journals, including Nous, Ethics and Philosophical Studies. You can read those papers here. She is currently writing her first book, which deals with issues in diachronic rationality. She also regularly writes shorter public philosophy essays—including publications in The Huffington Post and First Things—and gives public philosophy talks.
