I study representation theory, categorification, and algebraic combinatorics.
Representation theory is a field which focuses on studying algebraic structures like groups and algebras by focusing on ways to represent them as matrices acting on a vector space. This approach turns out to be extremely powerful and broadly applicable, partly because it allows us to use our thorough knowledge of linear algebra to investigate more nonlinear phenomena.
Algebraic combinatorics provides insights about algebraic structures by investigating associated combinatorial notions, such as symmetric functions and planar diagrammatics. These combinatorial methods are often the key to understanding difficult problems in representation theory.
My research statement is available here.
Some specific topics of recent interest for me:
- Heisenberg categorification
- Trace decategorification
- Symmetric functions
