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 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 Deligne-Lusztig theory.

Occasionally we also have a junior study group about Deligne-Mumford stacks and related topics.

This term (Lent 2019) I am giving supervisions for the part II course Algebraic Geometry.

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:
