During February 8-12, 2010 I visited the Centre International de Rencontres Mathematiques (CIRM) near Marseille, France. There I participated in conference on Dynamics and Computation.
As part of the conference I gave a 90-minute presentation on Degrees of Unsolvability and Symbolic Dynamics. My slides are available in several formats: PDF, PS.
A list of my recent and upcoming talks is available.
My publication list is available.
