Jag är biträdande professor i matematik vid institutionen för matematik och naturvetenskap vid BTH.

My research is centered on noncommutative geometry, with an emphasis on developing operator-algebraic models of geometric structures. A guiding theme is the noncommutative formulation of the principal-bundle framework of geometry using C*-algebraic methods. Complementing this analytic viewpoint, I study these constructions algebraically via graded structures—such as graded rings—and explore their connections with Fell bundles, graph C*-algebras, and groupoid C*-algebras.
