Mary Louise Gill is the David Benedict Professor of Classics and Philosophy. She joined Brown University in 2001 after teaching at the University of Pittsburgh. She has held visiting appointments at Dartmouth, Stanford, UCLA, UC-Davis, and Harvard. She has been a fellow at the Stanford Humanities Center, a visiting fellow at Clare Hall in Cambridge, a member of the Institute for Advanced Study in Princeton, and a fellow of the Radcliffe Institute for Advanced Study at Harvard. Gill's research interests center on ancient Greek philosophy and science. She is the author of Aristotle on Substance: the Paradox of Unity (Princeton University Press, 1989). She wrote the introduction for, and was co-translator of Plato: Parmenides (Hackett, 1996) and Philosophos: Plato's Missing Dialogue (Oxford University Press, 2012). Her current research project, "God of the Greek Philosophers," contrasts Plato's and Aristotle's conceptions of god as either creating or maintaining the world.
