Jeg leder for tiden et treårig forskerprosjekt med internasjonal mobilitet finansiert av Forskningsrådet. Jeg hadde opphold ved Stockholms universitet (august 2021 – mars 2023) og Universitetet i Potsdam (april 2023 – juni 2023) før jeg kom tilbake til Universitetet i Oslo.

Jeg fikk doktorgraden min ved Universitetet i Oslo. Veilederen min var Professor Nadia Larsen og medveilederen min var Professor Franz Luef.

Jeg organiserer en workshop ved Universitetet i Oslo ved navn Point sets: Dynamics, sampling and operator algebras fra 6. til 8. mai, 2024.

Jeg organiserer for tiden også C*-seminaret ved matematisk institutt.

Research interests

Forskningsinteressene mine tilhører harmonisk analyse og operatoralgebraer.
