My name is Tjerand. I’m a second year PhD student in cryptography at the Department of Mathematical Sciences at the Norwegian University of Science and Technology (NTNU) in Trondheim. My supervisors are Professor Kristian Gjøsteen and Professor Colin Boyd.
My main foci of research are lattice-based cryptography and zero-knowledge protocols. My interests also span the areas of secure multiparty computation, password-authenticated key exchange, electronic voting and anonymous credentials.
I graduated from NTNU with a B.Sc. in Mathematics in 2017 and a M.Sc. in Mathematics in 2020, respectively. I spent the academic year 2017-2018 at UC Berkeley, California, USA, and
I spent the fall of 2020 visiting the Aarhus Crypto Group in Aarhus, Denmark.
I’ve previously been working as a project manager at Lær Kidsa Koding (2015-17), as a university college teacher at Western Norway University of Applied Sciences (2017-20), and I had a 3 months internship in 2018 at the IoT-security company Intrinsic-ID in Eindhoven, NL.
