Dave Futer: Research
I study knots and links, as well as the 3-dimensional manifolds that
surround them. I was first drawn to this field by its visual nature
and strong geometric flavor. I like seeing things visually, and the
pictures of hyperbolic geometry play a significant role in my work.
Here is what I do, in a little more detail:

Visualization software:
- The KnotPlot
Site makes beautiful pictures, including both of the knot pictures on this page.
- Not Knot, a great
visual introduction to hyperbolic geometry
- Spend an hour or two playing with Jeff Weeks's
programs, and you'll understand the idea of a manifold.
