Johanne Haugland
I am a PhD Candidate in the Algebra group in the Department of Mathematical Sciences at the Norwegian University of Science and Technology (NTNU) with Prof. Petter Andreas Bergh as my supervisor and Prof. Steffen Oppermann as my co-supervisor. My research is in the general area of representation theory of algebras, and I am particularly interested in homological and categorical aspects of this theory.

Annual: Together with Karin M. Jacobsen and Sibylle Schroll, I organize the annual one-day conference
Flash Talks in Representation Theory, which takes place in January each year. See the conference webpage for registration and more information.
November 2020: Together with Aslak Bakke Buan, Sigrid Grepstad, Sibylle Schroll and Therese Strand, I organized the meeting "Women in Pure Mathematics in Trondheim".
Fall 2020: I participated in the Junior Trimester Program New Trends in Representation Theory at the Hausdorff Research Institute for Mathematics (HIM) in Bonn from September 1st to December 11th.

I have a pedagogical education and experience as a teacher in lower secondary school.
I have also taught the following courses at NTNU:
Fall 2018: TMA4100 Matematikk 1 (interactive lectures)
Spring 2019: TMA4150 Algebra
Spring 2021: TMA4150 Algebra (together with Øyvind Solberg)

Spring 2021: TMA4150 Algebra (together with Øyvind Solberg)
I have supervised teacher students in pedagogical training.
I was a mentor in a mentoring program for master students in Mathematical Sciences from August 2019 to June 2020, and I am also a mentor for new PhD students in mathematics at NTNU.
In mathematical sciences, I have supervised the following students:
Johan Vik Mathisen: Bachelor's thesis, An introduction to triangulated categories via the stable category of a Frobenius category
