Marianna Csörnyei

Marianna Csörnyei ( born October 8, 1975 in Budapest) is a Hungarian mathematician.

Csörnyei won the 1996 Hungarian Schweitzer Mathematics Competition in 1993 and received a gold medal at the International Mathematical Olympiad in Istanbul. She studied from 1994 at the Eotvos Lorand University, where she received her doctorate with György Petruska 1999 ( Studies in the geometric measure theory in the plane and in Banach spaces ). After that, she was a Research Fellow from 1999 and from 2004 professor at University College London and is since 2011 professor at the University of Chicago.

2009/2010 she was a visiting professor at Yale University and a visiting scientist at Cambridge ( Isaac Newton Institute and University ), Texas A & M University, the University of Jyväskylä in Finland, the University of Washington and the Pacific Institute for the Mathematical Sciences. 2003/ 04 she was at the Institute for Advanced Study.

It deals with real analysis, geometric measure theory and geometric nonlinear functional analysis. She proved the equivalence of various definitions of sets of measure 0 in infinite dimensional Banach spaces.

In 2002 she was awarded the Whitehead Prize and in the same year the Wolfson Research Merit Award from the Royal Society. In 2008 she was awarded the Philip Leverhulme prize. In 2010 she was invited speaker at the International Congress of Mathematicians in Hyderabad ( with Giovanni Albert, David Preiss differentiability of Lipschitz functions, structure of null sets and other problems ).

She was in the editorial board of Mathematika and that of the Journal and Bulletin of the London Mathematical Society.
