Elvira Lupoian

I'm a fourth year PhD student supervised by Prof. Samir Siksek and Dr Damiano Testa. I'm due to graduate in the summer of 2024.

My main interests are in arithmetic geometry and computational number theory.

I'm interested methods to compute explicit torsion points on Jacobians of curves of small genus and applications of these. Some of my current projects involve the study of modular curves, their rational and integral points, modular units and torsion subgroups of modular Jacobians.

I'm one of the organisers of "Modular Curves and their Arithmetic": MCA
