Philippe Michaud-Jacobs

Please note that prior to September 2021 I used the surname Michaud-Rodgers.Me and my dog

I am a fourth-year PhD student in number theory under the supervision of Professor Samir Siksek and Dr Damiano TestaLink opens in a new window. Previously, I completed my MMath degree at the University of Warwick.

Email: p dot rodgers at warwick dot ac dot uk (this email is indeed correct despite the name not matching).

Research Interests:

My research is focused on the explicit resolution of Diophantine equations, the study of low-degree points on modular curves, and how the two interact. More generally, I am interested in computational number theory and arithmetic geometry.
