My research interests include real and complex projective structures on surfaces, Teichmüller theory, hyperbolic geometry, and Kleinian groups. I integrate computer experiments and computer visualization into my research, and I develop open-source software to help others do the same.
For the Fall semester of 2013 I am visiting the Institute for Computational and Experimental Research in Mathematics as a research fellow in the program Low-dimensional Topology, Geometry, and Dynamics.

Note: These are old lectures. I now prefer to use chalkboards for my presentations.
