I am Chair of Jurisprudence at the University of Oxford and a Professorial Fellow at University College, Oxford. Before that I was a professor of philosophy at Rutgers University, New Brunswick, New Jersey in the United States. I’ve held visiting positions at the University of California, Los Angeles philosophy department and at the University of Chicago Law School. Before my life as a philosopher, I worked as a law associate on a (pro bono) death penalty case and several (non pro bono) product liability and medical malpractice cases.  I have a D.Phil. from the University of Oxford, a J.D. from Harvard Law School, and an A.B. from Dartmouth College. I continue to live part-time in New York and often give talks to audiences in the U.S.

My current academic interests concern the nature of normativity, the structure of values and reasons, practical reason, agency, rationality, population ethics, love, commitment, decision-making, and the self. My research on choice and decision-making has been profiled by various media outlets in the U.S., Canada, the U.K., Taiwan, Australia, Italy, Israel, Germany, Brazil, New Zealand, and Austria, and I have given lectures or been a consultant to a variety of industries and institutions including video gaming, pharmaceuticals, head-hunting, banking and finance, the U.S. Navy, the CIA, National Geographic, and the World Bank.

My philosophical interests are very broad, but my current research interests can be summarized by two cartoons.  For more detail, see my Selected Publications.
