Forskning

My research interests are in real and functionalanalysis on topics connected with maximal functions, spaces of functions of bounded variation, weighted inequalities. Recently, I have been working with problems related to factorizations and dual of weighted Cesaro spaces and spaces of functions of bounded variation.

Undervisning

I teach courses which are part of the Civil Engineering or Teaching education or Mathematics program, e.g. differential and integral calculus or several variable calculus, ordinary differential equations, functional analysis, etc. I am also involved in supervising of one PhD student.
