Courses being taught during Fall 2011
Math 123 (Abstract Mathematics I )
Math 132 (Discrete and Combinatorial Mathematics) Research interests: My main research interests are in the areas of algebraic topology and geometric group theory. In particular, I am interested in constructing group actions on manifolds. Publications:
