My research interests are in the
area of geometric topology and low-dimensional manifolds; in
particular, 3-manifolds and knot theory. In recent year I have been
working on problems concerning Dehn surgery on knots and links,
2-handle additions, and incompressible surfaces in 3-manifolds.
"Snappex" is a computer
program which combines Oliver Goodman's Snap (a variation of Jeff
Weeks' Snappea) and Harriet Moser's template to find candidates of
exceptional slopes for a given hyperbolic knot or link.
"MING" is a computer program used to minimize MD-energy of
polygonal knots, reduce number of edges, and draw/visualize their
3-dimensional pictures. It was written in C++, OpenInventor, and
