Robert C. Hughes is an Assistant Professor of Legal Studies and Business Ethics at the Wharton School of the University of Pennsylvania. He received his PhD in Philosophy from UCLA, and he has completed post-doctoral fellowships in the Department of Bioethics at the National Institutes of Health and in UCLA's Law and Philosophy Program. His research is in moral and legal philosophy and focuses on the ethics of obeying and enforcing the law and the possibility of consensual but wrongful exploitation.
