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 June 2024.

I am not on the academic job market anymore and will leave academic research upon graduation.
Feel free to contact me if you wish to know my reasons.

During my PhD, I was interested in: Until Spring 2022, I was also an organizer at WIQD, a network of women in Quantum.
