I am a PhD student of Tony Scholl, working on Galois actions on abelian varieties with complex multiplication. To be more precise, my research project involves the so-called plectic Galois group, a certain finite index extension of the absolute Galois group of $\mathbb{Q}$, and its action on CM abelian varieties.

Reading Groups

This term, I am participating in the number theory reading group on Lawrence-Venkatesh's proof of the Mordell Conjecture (arxiv).

Occasionally we also have a junior study group about Xiao-Zhu's paper on Cycles on Shimura Varieties.

This term (Michaelmas 2018) I am giving examples classes to the part III course on Lie algebras. The course webpage is here.

Here you can find a list of talks I have given (apart from the talks held at the reading groups above):


Here is a list of conferences and workshops I attended/plan to attend.

I am also frequently participating in the 'Kleine AG'. Topics include for example:
