Hi! My name is Bartosz, I am an assistant professor of mathematics at Mälardalen University in Sweden. Previously I was a lecturer in mathematics at KTH Royal Institute of Technology and a doctoral student at Lund University.
I like mathematical analysis in general. My research interests include complex function theory, harmonic analysis and operator theory.
