James Newton

As of September 2021, I have moved to Oxford. My new webpage is here.

Research:

I am interested in algebraic number theory, particularly (p-adic) automorphic forms and Galois representations.

Doctoral Students:

2018 – present Ashwin Iyengar.

2018 – present Pol van Hoften.

2020 – present Lambert A'Campo.

I am also second supervisor for several students, including Hanneke Wiersema.


Teaching:

I lectured Introduction to Number theory at King's from 2016 to 2020. I am now teaching Linear Algebra and Geometry II. All course materials are on KEATS.

I lectured Group Representation Theory (M3/4/5P12) at Imperial College London in Spring 2016. The homepage for the course is here.

I lectured a Part III course in Cambridge on Modular Forms in Lent term 2014. The homepage for the course is here.


Seminars:

Details for the London Number Theory Seminar are here. I am hosting pages for the Summer 2020 (online) seminar and study group.
