What I've done:
• Web pages for many past courses I have taught are here.
• Always SHARE: here is material I'm putting out in the world, such as articles, books, slide decks (and sometimes video or audio) from talks, etc. — I think of this as my own little contribution to the global intellectual commons.
• Here is an up-to-date CV.
• Click here for some interactive mathematics: an applet to visualize the geometry of fundamental domains for the action of cyclic subgroups of $PSL(2,\CC)$ on $\partial H^3_\RR$. Some fundamental domains in the interior of $H^3_\RR$ for this action are in a gallery.
