I am an assistant professor at Northeastern University.

My research is supported by NSF grant DMS-2302664 Categorical centers, cactus actions, and diagram algebras, 2023-2026. 

I work on questions in geometric and combinatorial representation theory, quantum algebra, knot theory and low-dimensional topology.

I completed my PhD at the University of Toronto in 2016, where my advisors were Dror Bar-Natan and Joel Kamnitzer. You can have a look at my CV for some more information.

Some Mathematica code I have worked on is available at the Knot Atlas.
