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 Postgraduate Research for the School of Mathematical Sciences. You can email me with questions about our PhD programme. Administrative queries on admissions can also be sent to Katie Hale, our Postgraduate Research Programme Officer.


Aram Dermenjian, Érika Roldán, Kris Shaw and I will run an instance of Queer and Trans Mathematicians in Combinatorics at QMUL on Thurs 6 and Fri 7 July 2023. Registration is now possible at that link. The deadlines are 5 May to apply for funding or to speak, and 30 June to register.

Felipe Rincón and Tara Fife and I run the weekly seminar of the Tropical and Geometric Combinatorics research group at QMUL.

Some past activities organised:

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


I have two current PhD students:

My former students are Zeinab Toghani was a recent postdoc of mine.


I share interests with the Algebra and Number Theory, Combinatorics, and Geometry and Analysis research groups at Queen Mary. It is the Algebra and Number Theory 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 been awarded EPSRC grant EP/X001229/1 Extensions of matroid Hodge theory, and plan to start it in May. 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.

Doctoral thesis
My thesis was titled Matroid polytope subdivisions and valuations. Aside from an introduction all its content appears in the papers above.
