Marianna Csörnyei

Department of Mathematics and the College

Marianna Csörnyei works in real analysis, geometric measure theory, and geometric nonlinear functional analysis. She proved the equivalence of the zero measure notions of infinite dimensional Banach spaces. She won a Whitehead Prize and a Royal Society Wolfson Research Merit Award in 2002, and the Philip Leverhulme Prize for Mathematics and Statistics for her work in geometric measure theory in 2008. Csörnyei spent the 2009–10 academic year at Yale University as visiting professor and was an invited sectional speaker at the International Congress of Mathematicians in 2010. She is contributing editor of the mathematics journal Real Analysis Exchange.

Her recent publications include “Differentiability of Lipschitz Functions, Structure of Null Sets, and Other Problems,” “Upper Conical Density Results for General Measures on $R^n$,” and “Points of Middle Density in the Real Line.”

Csörnyei received her diploma and PhD in mathematics from the Eötvös Loránd University in Budapest in 1999. She was the first place winner at the Schweitzer Competition in 1996 and the gold medalist at the Mathematical Olympiad in Istanbul in 1993.
