Pronouns: they/them

My main research interest is in noncommutative algebra, and in particular quantized coordinate rings / quantum algebras and their semi-classical limits. At the moment I'm mostly interested in H-primes in quantum matrices, and total nonnegativity in real matrices and the real Grassmannian.

For interested non-mathematicians

Here are some math outreach things I've created or been involved in; they're all aimed at mathematically-inclined people but don't require much specialist knowledge. Some of them even relate to my research!

For mathematicians

The following documents go into more detail about my research, and are listed in roughly increasing order of specialisation.
