I am a third-year PhD student under the supervision of Prof. Samir Siksek. I am currently working on the study of Diophantine equations over totally real fields, using the modularity of certain elliptic curves and the study of S-unit equations. However, my interests include more vast aspects of algebraic number theory, arithmetic geometry, and more recently isogeny-based cryptography.

I previously finished my MMath degree at the University of Oxford. My dissertation was on "Profinite Groups as Galois Groups" under the supervision of Prof. Nikolay NikolovLink opens in a new window.
