Background
I am a postdoc at the University of Oslo. I previously led a three-year researcher project with international mobility funded by the Research Council of Norway with stays at Stockholm University and the University of Potsdam. I obtained my PhD from the University of Oslo in 2020 with supervisor Professor Nadia Larsen and co-supervisor Professor Franz Luef.
Research interests
My research focuses on the intersection of harmonic analysis and operator algebras. I am currently particularly interested in sampling and interpolation problems, especially their connections to point set dynamics and aperiodic order. I am also interested in the structure of operator algebras arising from groups and groupoids.
