Talks

Feel free to reuse any of my slides or figures for your own presentations; all I ask in return is to give proper credit. I make most of my presentations in Keynote, with figures in SVG, PDF, and/or EPS format. I’m happy to share these upon request (see the bottom of the page for contact details).

Video recordings of some talks are available as indicated.
