Jana Sotáková

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

I am working on:

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

I am also an organizer at WIQD, a network of women in Quantum.

News

On April 5, I gave a talk at the ACCESS seminar talking about CTIDH: constant time CSIDH. You can check the slides.
In March 2022, I attended Isogeny-based Cryptography Workshop and gave a talk about Breaking DDH using genus theory. Slides here.
I will be a teaching assistant" for Kristin Lauter at the PCMI 2022 Graduate Summer School from July 17-August 6, 2022.
With WIQD, we are organizing a Annual WIQD Symposium: “Defying Gravity” on May 3, 2022! Sign up here!
