During November 5-8, 2009 I visited the University of Chicago to participate in a Workshop on Reverse Mathematics. I was one of the organizers of the workshop.

As part of the workshop I gave a 1-hour invited plenary talk on
** Measure-Theoretic Regularity, Degrees of Unsolvability, and
Reverse Mathematics**. My slides are available in two formats:
PDF, PS.

A list of my recent and upcoming talks is available.

My publication list is available.
