Overview

Bartosz completed his PhD at Wroclaw University of Science and Technology, Poland, in 2016. He was honored the Award of the Prime Minister of the Republic of Poland for his doctoral dissertation. After graduating, Bartosz worked for 2 years as an Assistant Professor at Wroclaw University of Science and Technology, and in 2018 he decided to move to the US to start a postdoctoral position at Indiana University Bloomington. He stayed at IU for the next 5 years until in the Fall 2023 when he started a tenure-track position at Franciscan University of Steubenville. His research interests include real harmonic analysis, in particular the theory of non-trigonometric orthogonal expansions, discrete harmonic analysis and ergodic theory, with special focus on pointwise convergence problems.
