Simran Tinani

University of Zurich


I am currently a Ph.D. student at the University of Zurich working under the supervision of Professor Joachim Rosenthal. Starting September 2021, I am, in addition, a Doctoral Fellow at the Cyber Defence Campus (CYD) of the Armasuisse. The title of my project under this fellowship is "Nonabelian Groups in Cryptography".

Research interests

Applied Algebra, Group-based Cryptography, Number Theory
