I am an associate professor in mathematics at Cambridge and a fellow at John's. I study algebraic geometry. 

My work focuses on tropical geometry in moduli theory and enumerative geometry. You can get a flavour for it from this Quanta article and these more detailed articles: I, II, and III. Moduli theory is an enchanting subject: see Rahul's compilation of reflections. 

I am teaching Part II Algebraic Geometry this term. I taught Part III Algebraic Geometry last term. 

Cambridge Algebraic Geometry: I supervise PhD students Ajith, Patrick, Siao Chi, Siddarth (with Melody), and Terry. Thibault is a postdoctoral fellow in the group. You can get a sense of what people work on here. The broader group includes postdoctoral fellows Tim and Eloise.  Mark and his students have similar interests. We run a seminar. 

Undergraduates: I help coordinate the Cambridge Summer Research in Mathematics Programme. You can read about work of my former students here.

Editorial: I am an editor for the Mathematical Proceedings of the Cambridge Philosophical Society.

My work is currently supported by the EPSRC.
