He went to the University of Warsaw for his undergraduate and stayed there until 2004, working up through the ranks to an associate professor after receiving his Ph.D. in 1994 under the supervision of Bogdan Bojarski. As of today, he has been a professor of mathematics at the University of Pittsburgh for a full twenty years. He was elected as a Fellow of the American Mathematical Society in 2017. In recognition of his contribution, he was awarded the prestigious Sierpiński Medal by the Polish Mathematical Society in 2021. Winning this award has placed him among the ranks of distinguished mathematicians including Paul Erdős, Stanisław Ulam, and Benoit Mandelbrot.
