## Research

My research is in low-dimensional topology and geometry, especially invariants of knots and links in three and four-manifolds. I often use Heegaard Floer homology or Khovanov homology, and many of my results involve local operations on knots like crossing changes, band surgeries and mutations. I have a secondary research interest in the applications of topology to physical systems, for example, how to model and characterize enzymatic actions on circular DNA molecules.

Here is a link to my papers on the arXiv. Authorship on all articles is alphabetical.

## Undergraduate Researchers

### Research opportunities for undergrads in Fall 2021 -- Summer 2022

**Project description:**

Knots and links are embeddings of closed loops in three-dimensional space. Knot and link invariants are mathematical objects that capture topological and geometric information about the link and its three-dimensional complement. This project seeks to advance our mathematical understanding of basic operations on knots and links, to explore the relationships between invariants of knots and three-manifolds, and to leverage these developments toward knot-theoretic models of DNA recombination mediated by enzymes. The central hypothesis of the proposal is that knot theory provides a rigorous mathematical framework with which to investigate molecular knotting and entanglement in DNA.

Students with a genuine interest in topology and geometry or some background in linear algebra or coding will be most successful. Prior knowledge of knot theory is not required, and essential skills can be learned along the way. There are some funds to pay students an hourly wage. Students from underrepresented groups are especially encouraged to apply.

Any VCU undergrads or grad students who are curious about this research project, a summer project, or interested in independent study, please get in touch with me by email (moorea14 at VCU dot edu).

## Topological Molecular Biology at UC Davis

At UC Davis, I held a joint appointment in the Topological Molecular Biology lab, in the department of microbiology and molecular genetics. Part of my research at UC Davis was funded by the NSF, with PI M. Vazquez.
