S. Krishnan [academic]

I'm an assistant prof at Ohio State.

Algebraic topology provides methods for teasing out robust , global structure from local information. I am particularly interested in directed algebraic topology, an algebraic topology for local information that has a directional nature (like vector fields or semigroups), and its uses in such traditional applied subjects as optimization.
