## Research interests:

My general research revolves around low-dimensional groups. I am particularly interested in one-relator groups, free-by-cyclic groups and graphs of free groups. Within these classes I mainly think about hyperbolicity, coherence, the conjugacy problem and the efficiency of the word problem. I am also interested in compression and its applications to computational questions in groups.

## Articles:

1) Residually rationally solvable one-relator groups, (arXiv).

2) Group rings of three-manifold groups (with Dawid Kielak, arXiv, Proc. Amer. Math. Soc.).

3) On the coherence of one-relator groups and their group algebras (with Andrei Jaikin-Zapirain, arXiv, Alexander Engel’s blog).

4) Virtually free-by-cyclic groups (with Dawid Kielak, arXiv, Geom. Funct. Anal., Alexander Engel’s blog).

5) Hyperbolic one-relator groups (arXiv, Canad. J. Math.).

6) One-relator hierarchies (arXiv, Alexander Engel’s blog, to appear in Duke Math. J.).

7) The fully compressed subgroup membership problem (arXiv, Journal of Algebra).

8) On the intersections of finitely generated subgroups of free groups: reduced rank to full rank (arXiv).

## A database:

I am putting together a database of one-relator groups. More information can be found here.
