At IMADA, I have been a TA in the following courses

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 and seminars on topics such as Cryptology, 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.
