Robin Visser

I am a second year PhD student in algebraic number theory, under the supervision of Prof. Samir Siksek and Prof. David Loeffler. My current interests include studying both elliptic and hyperelliptic curves and their Jacobians, although I've also enjoyed playing around with various aspects of computational and analytic number theory.

Background: After finishing my B.Sc. (Hons) degree at Stellenbosch University in 2018, I completed my MASt (Part III) at the University of Cambridge in 2020, where I also wrote a short essay on large prime gaps. For more information on my background, see my CV.
