Research

I am interested in string link infection, string link operators, and the maps they induce on concordance groups.

A string link can be thought of as an embedding of m disjoint intervals into a thickened disk so that the i th endpoint at the top is connected to the i th endpoint at the bottom.

String Link Representation of the Hopf Link

Given a knot K, an embedded disk D that intersects K only in m disjoint subdisks, and an m-component string link L, we can infect K by the string link L along D by tying the strands intersecting the subdisks in the pattern of L. The following images illustrate first R and D, then L, and finally infection of R by L along D.

If we fix the knot K and the disk D, which we call a pattern, we can consider them as an operator from the set of m-component string links to the set of knots. This induces a map from the m-component string link concordance group to the knot concordance group. My research focuses on the the use of concordance invariants to study properties of these maps.
