Jana Sotáková

I am a PhD student of Christian Schaffner, Serge Fehr and Peter Bruin at Institute of Logic, Language and Computational the University of Amsterdam (ILLC) and a part of the QuSoft Crypto group. I started my PhD in 2019 and expect to graduate in 2023.
I am working on:

post-quantum cryptography, especially isogeny-based cryptography,
computational number theory,
quantum algorithms used for cryptanalysis.

News

Our paper "Explicit connections between supersingular isogeny graphs and Bruhat--Tits trees" with Laia Amorós, Annamaria Iezzi, Kristin Lauter and Chloe Martindale is on eprint!
The current version is also accessible here.
I have given two talks about the paper and you can see my exposition in these notes here. Please contact me with any comments!
I am giving a talk at the RTG seminar at Clemson University on March 22, 2021.
I will be a TA at the (online) PCMI 2021 Graduate Summer School (July 26-30, 2021) for the course of Kristin Lauter on Supersingular Isogeny Graphs in Cryptogprahy.
In Spring 2021, I am running a reading group at QuSoft on quantum algorithms for isogeny problems.
I am currently updating this website.
