This is my personal website here you find my academic writings, email adress and so on.

I am a second-year PhD-student at the math department at NTNU in Trondheim under supervision of Drew Heard. My main interests are (higher) category theory, stable homotopy theory and homological algebra. I have also recently become interested in representation theory and equivariant homotopy.

*Chromatic homotopy theory, from the perspective of formal groups*. Written notes I did as part of a PhD level seminar course I did at NTNU spring 2023. These notes acted as talking points for the seminar I gave as my exam.*The Q-shaped Derived Category*. My masters thesis supervised by Henrik Holm at the University of Copenhagen in block 3 and 4 2021/2022.*Idempotent algebras and stable recollement*. Notes from a talk I gave in “*Topics In Algebraic Topology*” at the University of Copenhagen in block 2 2021/2022.*Monadicity of the Bousfield-Kuhn functor*. Notes from a talk I gave in “*Topics In Algebraic Topology*” at the University of Copenhagen in block 2 2020/2021.*Stable infinity-categories*. Notes from a talk I gave in “*Topics In Algebraic Topology*” at the University of Copenhagen in block 2 2020/2021.*On Homotopy Colimits*. My Bachelors thesis supervised by Piotr Pstrągowski at the University of Copenhagen in block 3 and 4 2019/2020.*Tannaka Duality*. Project out of course scope supervised by Thomas Wassermann at the University of Copenhagen in block 3 and 4 2018/2019.
