She received her Ph.D. in Philosophy from Princeton University in 2009. Her primary research interests are in decision, game, and rational choice theory. Her book Risk and Rationality (Oxford 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 is currently working on applications of this work to central questions in ethics, including the question of how resources in a society should be distributed and the question of when one is allowed to take a risk that affects other people. Other topics she has written on include the relationship between assigning probability to a hypothesis and believing that hypothesis outright, and the conditions under which one ought to stop one’s search for evidence.
