Daniela Kühn

Daniela Kühn (* 1973 ) is a German mathematician . She is particularly concerned with graph theory and extremal combinatorics .

Life

Kühn studied mathematics in Chemnitz (Diploma 1998) and Cambridge (Certificate of Advanced Studies in Mathematics 1997 in the Tripos). In 2001 she did her doctorate at the University of Hamburg under Reinhard Diestel ( Cycles, Minors and Trees ), was a post-doctoral student in Hamburg and at the Free University of Berlin and completed her habilitation in 2003 in Hamburg. In 2004 she became a Lecturer and in 2010 Senior Lecturer and Mason Professor of Mathematics at the University of Birmingham .

In 2011, together with Deryk Osthus and Richard Mycroft , she proved Sumner's conjecture about tournament graphs (every tournament graph of 2n-2 nodes contains any oriented graph with n nodes).

In 2003 she and Deryk Osthus received the European Prize in Combinatorics for many results in the central division of graph theory, which deals with graph minors and random structures, especially in connection with Hadwinger's conjecture . In 2014 Kühn and Osthus received the Whitehead Prize . In 2002 she received the Richard Rado Prize from the DMV for her dissertation .

In 2014 she was invited speaker at the International Congress of Mathematicians in Seoul ( Hamilton cycles in graphs and hypergraphs: an extremal perspective , with Deryk Osthus).
