Welcome!  I am an analytic philosopher that focuses on Philosophy of Science, Philosophy of Biology, and Philosophy of Race.  Currently, I am the Robert S. Blank Presidential Associate Professor of 
Philosophy at the University of Pennsylvania.  I obtained my PhD in Philosophy and an MS in Biology from Stanford University.  My current interests in philosophy lie in the metaphysics of race, the nature of biological populations, and the natural kind debate.  Feel free to browse my page to learn more about me and my philosophical interests and projects.
