About me:
I am an associate professor at the Institute of Mathematics of the Polish Academy of Sciences and a full professor at the Mathematical Institute at the University of Wrocław.
I completed my PhD in Mathematics in 2014 via a co-tutelle agreement beetween the University of Wrocław and Scuola Normale Superiore, Pisa. My PhD thesis was entitled 'Multivariate Spectral Multipliers' and it is avaliable
here .
I obtained my
Habilitation degree from the University of Wrocław in June 2019.
I received the title of professor in May 2024.
The main area of my research is harmonic analysis. I am especially interested in high-dimensional phenomena that arise as the dimension tends to infinity. I am also interested in related aspects of operator theory, PDE, analytic number theory, and ergodic theory.
