I teach Philosophy at Dartmouth College. My primary interests are in philosophical issues raised by emerging technologies, such as whether it is ethical to enhance people (pharmaceutically, genetically, or otherwise) and whether the ongoing commercialization of reproduction (such as outsourcing pregnancy) is morally problematic.

I received my doctorate in Philosophy from MIT and moved to the Upper Valley in 1991. I live with my partner, our kids, two dogs, a cat, a turtle, and a fish in Thetford, Vermont.

When I'm not working, I like to make furniture, and to spend time with my family and friends.
