Dr. Mary Hirschfeld works on the boundaries between theology and economics using an approach rooted in the thought of St. Thomas Aquinas. She has written on economic inequality, the technocratic paradigm, the financial crisis and the common good. She completed a Ph.D. in economics (Harvard University) under the direction of Lawrence Summers and Jeffrey Williamson, and a Ph.D. in Moral Theology (University of Notre Dame) under the direction of Jean Porter. Her research is on the boundary between economics and theology, culminating in her book Aquinas and the Market: Toward a Humane Economy (Harvard University Press, 2018).
