ExpertiseGeometric topology, particularly knot theory and its applications to 3- and 4-manifolds
ProfileThe set of knots and links in 3-dimensional space is a group under a certain 4-dimensional equivalence relation called concordance. Broadly speaking, my research so far has sought to understand the structure of this group. The study of knots and links under this equivalence relation is related to the study of 4-manifolds; the fourth dimension is particularly difficult to study, since it is in some sense a boundary case between low and high dimensions - there are enough dimensions for the manifold topology to exhibit complex behavior, but not enough space for our usual tools to work.
