I am a PhD fellow at the Department of Mathematics and Computer Science (IMADA) and Digital Democracy Center (DDC) at the University of Southern Denmark (SDU). The title of my project (and the group that I am part of) is Trust and News Authenticity, and our goal is to provide a novel approach to combating misinformation. My excellent supervisors are Joan Boyar, Kim Skak Larsen, Ruben Niederhagen, and Claes de Vreese.

The Axiom of Choice is obviously true, the well-ordering principle obviously false, and who can tell about Zorn's lemma?

2.1 Master's Thesis: Oblivious Transfer in Quantum Cryptography

Advisor: Professor Joan Boyar, University of Southern Denmark.
External examiner: Professor Ivan Damgård, Aarhus University.
Abstract: We give a broad introduction to quantum mechanics and its implications in computer science, together with a thorough investigation of sampling games in a quantum setting. With this toolkit, we show that the BBCS92 protocol for the cryptographic primitive oblivious transfer is secure against arbitrary quantum adversaries. Finally, we show how to create bit-commitments from post-quantum one-way functions.
  Graded 12 on the Danish 7-point grading scale (Equivalent ECTS mark: A).

Between February 2020 and December 2021, I hosted the homework cafe "Matematikcafeen" at IMADA, approximately once per week. "Matematikcafeen" is an open cafe where students following courses at IMADA can come to discuss any problems they might find difficult with a more experienced student.

I have also facilitated various workshops on LaTeX and Emacs.

Finally, from August 2017 to July 2018, I was involved in organising the UNF Matematikcamp 2018, a week-long event for Danish High School students with an interest in mathematics. Together with a fellow university student, I organised an introductory course in Linear Algebra. This involved writing material for the course, and planning and hosting both lectures and exercise sessions.
