(Ph.D., Princeton University). Her primary research interests are in decision, game, and rational choice theory. Her work focuses on how an individual ought to take risk into account when making decisions and how we should best model risk attitudes within decision theory. She argues for a more permissive theory of rationality than is standardly assumed: her theory is a mathematical generalization of the orthodox theory. She is currently working on a book in this area, entitled Risk and Rationality. Further work in formal epistemology explores the questions of when an why one ought to stop one’s search for further evidence. In the philosophy of religion, she has written on the question of what faith is, and under what circumstances it is rational to have faith. She also has more general interests in the philosophy of religion, and in epistemology.
