Who am I

I am a third-year PhD-student at the math department at NTNU in Trondheim under supervision of Drew Heard. I am broadly interested in stable homotopy theory, tensor triangulated geometry and their relationship with spectral algebraic geometry and synthetic spectra.

Expository writing

• 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.
