Hi there! I'm a graduate of the University of San Francisco, BS Mathematics, and a graduate student and TA at San Francisco State.

I'm particuarly interested in topology, and it is in this area I intend to contribute to Proofwiki.

Pages and Such
I've done a lot of topology, some number theory, differential geometry...  just a bunch of stuff.

Projects
I'm working on putting all of my lecture notes in topology up here, drawing heavily on 3 reference texts: Guillemin and Pollacks Differential Topology, Bredon's Topology and Geometry , and Hocking and Youngs Topology.

I hope to get cracking on knot theory soon-ish.

Pages I've Written
I keep this for my own reference, so I can keep track of what I should finish and what I've abandoned and what I would like to still do.
