Todd received his Ph.D. in philosophy from the London School of Economics. Before LSE, he completed an M.Phil. in political theory at Oxford University. His doctoral dissertation focuses on theoretical and practical issues in the ethics of killing, and a few other normative matters involving death. On the theoretical side, he has worked on the relationship between the wrongness of killing and the badness of death and about how killing and dying relate to the metaphysics of time. On the more practical side, he has worked on the question of the extent of one's right to self-defense in the context of war and the moral duties people incur in virtue of killing others.
Todd's interdisciplinary ethics fellowship is in partnership with the Stanford Institute for Human-Centered Artificial Intelligence, where he will work on moral issues concerning the development and use of autonomous-weapons systems in war.
