I am a researcher at the University of Oslo leading a three-year researcher project with international mobility funded by the Research Council of Norway. Before returning to the University of Oslo I was a visiting researcher at Stockholm University (August 2021 – March 2023) and the University of Potsdam (April 2023 – June 2023).
I obtained my PhD from the University of Oslo in 2020. My supervisor was Professor Nadia Larsen and my co-supervisor was Professor Franz Luef.
I am organizing a workshop at the University of Oslo May 6–8, 2024 titled Point sets: Dynamics, sampling and operator algebras.
I currently organize the C*-seminar at the University of Oslo.
Upcoming:
May 6–8: Point sets: Dynamics, sampling and operator algebras, workshop at the University of Oslo.
May 13–16: Visit from Eduard Vilalta, Chalmers University of Technology and Gothenburg University.
June 17–20: Noncommutativity in the North (MikaelFest), symposium at Chalmers University of Technology and Gothenburg University.
September 12–13: Nasjonalt matematikermøte 2024, Oslo.
Research interests: My research interests are in operator algebras and harmonic analysis. Currently I am interested in sampling problems originating in harmonic analysis and how they can be approached using C*-algebras and von Neumann algebras of associated groups and groupoids.
