My name is Tjerand. I am a third year PhD student in cryptography at the Department of Mathematical Sciences at the Norwegian University of Science and Technology (NTNU) in Trondheim, where I am a member of the NTNU Applied Cryptology Lab. My supervisor is Professor Kristian Gjøsteen. I am also working as a cryptography advisor at Pone Biometrics.

I am currently visiting Professor Jonathan Katz at the University of Maryland, USA.

My main foci of research are lattice-based cryptography and zero-knowledge protocols. My interests also span the areas of secure multiparty computation, homomorphic encryption, password-authenticated key exchange, electronic voting and anonymous communication.

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 at Aarhus University, Denmark.

I have 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.
