I am currently a postdoctoral fellow at the Mathematical Sciences Institute of the Australian National University in Canberra. Before this I held a postdoctoral fellowship at the Mathematical Sciences Research Institute, an NSERC post-doc at the Fields Institute, and a member position at the Institute for Advanced Study.

I completed my PhD in 2011 at the University of Toronto where my advisor was Dror Bar-Natan.

# Research interests

I am interested in the intersections and connections between algebra, topology and combinatorics. I study relationships between quantum topology and Lie theory, combinatorial and topological aspects of categorification, and occasionally graph theory.

For more detailed information, you can take a look at my research statement, publications, talks and CV.

# Collaborators

- Dror Bar-Natan and I do knot theory and Lie theory.
- Tony Licata and I work on categorification.
- Stavros Garoufalidis and I think about graphs.
- Michael McBreen, Vivek Shende and I work on combinatorial aspects of non-abelian Hodge theory.
- My partner Stephen Morgan does geometric representation theory and tells me about it sometimes. We collaborate on raising our son Oliver.
