## Main Research interest: Topology & Geometry

Ideas combining low-dimensional topology & geometry, often with a bit of physics thrown in. Some examples:

- helicity of 3-dim. (and 2n+1-dim.) vector fields
- writhe of knots & other geometric/physical knot theory concerns
- ropelength of knots & its applications
- symmetries of knots & links

## Voting Theory

In my spare time, I think about voting theory.

- the geometry (polytopes) & combinatorics (posets) of weighted voting
- a new power index
- applications of topology to ranking
- exit polls: my first-year seminar conducted (successfully!!!) an exit poll for Forsyth County in the 2008 election
