Piotr Koszmider is a professor of mathematics at the Mathematical Institute of the Polish Academy of Sciences in Warsaw. He received his Ph.D. at the University of Toronto in 1992 and since then has done mathematics in Canada, Israel, the US, Brazil and recently in Poland.

His mathematical interests have evolved starting with forcing theory, Boolean algebras and stepping-up principles, through topology to the present applications of forcing, combinatorial set theory and analytic topology in Banach spaces and algebras of operators acting on them.
