I joined the Duke faculty in 2000.
Previously I was professor of philosophy at Dalhousie University in Canada, Syracuse University, University of California, Riverside and at the University of Georgia, in the US. I have also been a visiting professor and/or fellow of the Center for Philosophy of Science at the University of Minnesota, as well as the University of California, Santa Cruz, Oxford University (Balliol College) and the Research School of Social Science of the Australian National University. Here at Duke, I am co-director of the Center for Philosophy of Biology, along with Robert Brandon, Dan McShea and Fred Nijhout.
Along with Professor Martha Reeves of the Sociology Department I co-direct Duke's summer program on Globalization in Geneva. Search for Duke University Global Education for Undergradutes Duke in Geneva, http://globaled.duke.edu/Programs/Summer/Duke_in_Geneva for more information on this programs.
My interests focus on problems in metaphysics, mainly surrounding causality, the philosophy of social sciences, especially economics, and most of all, the philosophy of biology, in particular the relationship between molecular, functional and evolutionary biology.
