## About me

I am currently a lecturer at The University of Queensland. I received my Ph.D. in Mathematics from University of California, Davis in 2015 under the guidance of Anne Schilling. From 2015 to 2017, I was an RTG Postdoctoral Associate as part of the combinatorics group at the University of Minnesota, specifically under the mentorship of Pavlo Pylyavskyy. From 2017 to 2019, I was a Postdoctoral Research Fellow at The University of Queensland under the mentorship of Ole Warnaar.

## Research

My primary research interests are in combinatorics and representation theory,
specifically in the area of crystals and (Kac–Moody) Lie algebras.
My research focuses on a specific class of finite crystals for affine Lie
algebras called *Kirillov–Reshetikhin (KR) crystals* and
combinatorial objects called rigged configurations.
The (conjectural) bijection between tensor products of KR crystals and
rigged configurations of objects arose from statistical mechanics and has
led to applications in soliton cellular automata, a generalization of the
box-ball system. In particular, this would give a (combinatorial) proof of
the \(X = M\) conjecture. Characters of tensor products of KR crystals also
have deep connections with other areas of mathematics, including
(non)symmetric Macdonald polynomials
and Q-systems. Ben Salisbury
and I have also generalized rigged configurations to be a model for highest
weight crystals, where they appear to be a very natural model.

Additionally, I am interested in generalizations of crystals; specifically in geometric crystals, a rational lifting of crystals, and crystals for Lie superalgebras and Borcherds algebras. Recently I have been working on developing a theory of crystals related to the K-theory of the Grassmannian and Schubert calculus. I have additional interests in combinatorial Hopf algebras, which includes symmetric functions, Coxeter and Artin groups, and Hecke algebras.

## Other stuff

I previously co-organizing the QFT Seminar at the University of Queensland in 2020. For more information, see the main QFT seminar website.

I have also been a developer for the open-source mathematical software SageMath since 2010 and have been programming in various languages (C, C++, C#, Java, Python, etc.) since 2001. For books on SageMath, see Computational mathematics with SageMath (also available from a traditional publisher) and Gregory Bard's book.
