Teaching Activities

My teaching experience covers several areas in analysis as well as courses in algebra, geometry, number theory, probability theory, and topology. Today my teaching makes use of the methods of flipped learning.

Research groups and research projects

My research is focused on the regularity methods and the fine topology related to the nonlinear potential theory in metric spaces and in variable exponent spaces.
