Here are a few of the scholarly, semischolarly, and popular talks that I've given to various kinds of audiences. Some of these files are video, others just audio. If a talk doesn't open properly in one browser, try opening it in another.

I apologize for all the images of my ugly face.  When the video camera is trained on you the whole time, it's hard to find another image to illustrate the talk.
