Picture of Artur Sowa

Artur Sowa PhD Professor Department of Mathematics and Statistics

I received an M.Sc. from Warsaw University in 1990, specializing in complex analysis and differential geometry. I received my Ph.D. degree from The City University of New York in 1995. My doctoral thesis focuses on problems of mathematical physics and differential geometry. In more recent years my interests turned to harmonic analysis and quantum theory, as well as quantum technologies.
