(Ph.D., Princeton University). Her primary research interests are in decision, game, and rational choice theory. Her book Risk and Rationality (OUP, 2013) concerns how an individual ought to take risk into account when making decisions. It vindicates the ordinary decision-maker from the point of view of even ideal rationality. She also has research interests in the philosophy of religion, ethics, and epistemology. Some topics she has written on include distributive justice; the relationship between assigning probability to a hypothesis and believing that hypothesis outright; the conditions under which one ought to stop looking for more evidence and make a decision; and the nature of faith, both in the religious and the more mundane sense.
