Hi. I'm an Associate Professor of Philosophy at the University of San Diego, a co-director of USD's Institute for Law and Philosophy, and the founder of and frequent contributor to the Bleeding Heart Libertarians blog.

My research interests are generally in the intersection of ethics, law, and economics, with two specific areas of focus. The first involves the proper understanding and normative status of liberty and political libertarianism.  The second has to do with the nature and moral significance of exploitation for individual ethics and political institutions.

I currently have two book projects in progress. The first is a anthology of new essays on exploitation, currently under contract with Oxford University Press. The second, A Brief History of Libertarianism, attempts to trace libertarian thought from its origins in figures like Grotius and the Spanish Scholastics to more contemporary figures like Rothbard, Hayek, Rand and Nozick. I am writing this book with John Tomasi of Brown University, and it is currently under contract with Princeton University Press.

The second edition of my textbook, Arguing About Political Philosophy was published by Routledge in May, 2014.

In the Spring 2015 semester, I am teaching Business Ethics and Political Philosophy.
