I am an assistant professor in the Legal Studies and Business Ethics Department at the Wharton School of the University of Pennsylvania. I received my Ph.D. in philosophy from UCLA in 2010. I have completed post-doctoral fellowships in the Department of Bioethics at the National Institutes of Health and in the Law and Philosophy Program at UCLA. I have also been a lecturer in the UCLA Department of Philosophy.

My work is at the boundary between moral philosophy and legal philosophy. I defend non-consequentialist ethical constraints on individuals, firms, and the state, focusing on these three areas:

  1. Ethical limits on law enforcement. Sometimes, I argue, government should make a law and demand that people follow it, but it should not enforce that law coercively. In some social circumstances, there are important criminal laws that should not be enforced with the threat of imprisonment.
  2. Law as an ethical constraint on individuals and firms. I examine the extent to which there is a moral obligation to obey the law and when, if ever, it is morally permissible to treat fines or other legal sanctions as costs of doing business. I am particularly interested in ways the democratic or non-democratic character of a legal system affects the moral obligation to follow the law.
  3. Ethical constraints on voluntary transactions. Informed consent is not always enough to make an economic transaction ethical. I defend under-appreciated ethical constraints on fair transactions, including strong standards of workplace safety.
