Personal Webpage


I am an EPSRC postdoctoral fellow in mathematics, specialising in number theory, and in particular in Iwasawa theory. I previously held a Heilbronn research fellowship at Imperial College London from 2016-2019, after completing my PhD at Warwick in 2016.

My research is supported by grant EP/T001615/1.

My personal homepage is more likely to be up-to-date than this one.

Teaching, 2019-20: In January-March 2020, I gave an extended version of my course with Joaquin Rodrigues on an introduction to p-adic L-functions at the TCC in Warwick. The course page is here.
