I am an economist and a research fellow with the Harvey L. Neiman Health Policy Institute. My research interests include law and economics, health economics, and the economics of crime. I am particularly interested in informal markets and the secondary consequences of labor regulation. I am also an affiliate scholar of the Center for Micro-Economic Policy Research at George Mason University.

I have worked as the Economics Research Manager for the American Road and Transportation Builder Association. Previously, I also worked as a reporter for the PA Independent and interned at the Mackinac Center for Public Policy and the Institute for Justice. In my spare time I enjoy reading science fiction, Scottish highland dancing, and travelling.
