Teaching

I am teaching the following courses in Spring 2013. Information for students taking these courses can be found on Angel.

• MAT 202 Linear Algebra
• MAT 124 Functions and Modeling II

Office Hours: M 3:30-4:30, T/TH 3:15-4:15, or by appointment

Research

My current work is on real projective structures on manifolds and orbifolds. More generally, I am interested in geometric topology and geometric group theory.

Surfaces

In Spring of 2010 I visited Cornell University and started building surfaces with Bill Thurston. For more examples see the gallery.
