Hi! I'm Matti. I'm a postdoctoral researcher at the University of Hamburg, working with the research group of Prof. Christoph Schweigert.

In Autumn 2025, my postdoctoral stay is funded by the Lundström-Åmans stipendiestiftelse, and from 2026, it will be funded by the Knut and Alice Wallenberg Foundation.

I received my PhD in 2025 from Uppsala University. My supervisor was Prof. Volodymyr Mazorchuk, and my co-supervisor was Prof. Julian Külshammer.

My primary research interest is the study of module categories over monoidal categories, in particular over tensor categories or as (finitary) 2-representations. I am very interested the applications of such structures in representation theory, Hopf theory and in field theories. I'm also interested in such applications of other categorical structures, such as duoidal categories, multicategories or double categories.
