Teaching and tutoring

In Semester A of 2024/25 I taught the Professional Placement Tutorial, MTH5200A.

Administration

I am the head of the Centre for Combinatorics, Algebra and Number Theory (CeCANT). The role will be deputised to Felix Fischer for January – June 2025.

Activities

Thomas Bartsch, Madeleine Moore, Daniel Ratliff, and I are organising a one-day event The Queer Experience in Mathematics at Loughborough University on Wed 2 July 2025, centred on discussing what are the current support needs for LGBTQ+ mathematicians in the UK. 31 May is the deadline to apply for travel funding or to present a provocation.

I will be on sabbatical from January to June 2025, based at the Special Year on Algebraic and Geometric Combinatorics at the IAS and the Thematic Program in Commutative Algebra and Applications at the Fields Institute.

The weekly seminar of the Combinatorial Algebraic Geometry research group at QMUL is currently running.

Some past activities organised:

I have profiles at 500 Queer Scientists and LGBTQ+ STEM.

Group

I have three current PhD students:

and one current postdoc: My former students are Zeinab Toghani was a recent postdoc of mine.

Research

My research interests are principally in algebraic combinatorics, especially where commutative algebra or algebraic geometry apply, including matroid theory and tropical geometry.

I hold EPSRC grant EP/X001229/1 Extensions of matroid Hodge theory. I have previously held EPSRC grant EP/M01245X/1 Algebra and geometry of matroids and Horizon 2020 Marie Skłodowska-Curie grant No 792432 Tropical differential geometry.
