Research area: Analysis

PhD in Mathematics obtained at University of Helsinki (2011)


I am a senior postdoctoral researcher working in the Analysis group of the University of Barcelona. My position is funded by BGSMath.

I got PhD in 2011 at the University of Helsinki, where my advisors were Jari Taskinen and Jani Virtanen. Since then, I have worked as a postdoc in Helsinki, Stockholm and Joensuu, and now in Barcelona.

I am interested in operator theory in function spaces. More precisely, I am working on analytic Hardy and Bergman spaces and their operators, as well as applications to other areas of mathematics.
