Teaching and tutoring

In Semester B, I am teaching MTH4104, Introduction to Algebra.

In previous years I have taught an advanced graduate module on Enumerative Combinatorics at the London Taught Course Centre.


I am the Director of Undergraduate Admissions for the School of Mathematical Sciences. Queries regarding undergraduate admissions should be sent to

I have two current PhD students:

and one completed:


I share interests with the Algebra, Combinatorics, and Geometry and Analysis research groups. It is the Algebra group which I am formally affiliated with.

My research interests are principally in algebraic combinatorics, especially where commutative algebra or algebraic geometry apply, including matroid theory and tropical geometry. I have made a successful proposal as PI of a Marie Skłodowska-Curie fellowship titled Tropical differential geometry, which will begin later this year. Prior to this I held EPSRC grant EP/M01245X/1 Algebra and geometry of matroids.
