Personal Webpage


I haved moved: as of September 2022, I am an Assistant Professor of Pure Mathematics at Nottingham.

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

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

Teaching 2021/22:  MA4M3 Local Fields (Term 2)

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.

On 27th July, I organised an informal one-day workshop at Warwick. For more details, see [ here ].
