I have moved from the University of California, Riverside, to Williams College, and my web site has moved with me.
The new site is at http://redcocoon.org
If you are looking for something on one of my old UCR course pages, I have taken these down now that I am no longer teaching these courses at UCR. I will be rebuilding some of these pages at Williams, but in the meantime, feel free to email me if there is something specific you are looking for. My new home page also contains my new email address.
