Joachim Cuntz

Joachim Cuntz (born 28 September 1948 in Mannheim) is a German mathematician, currently a professor at the University of Münster.

Work
Joachim Cuntz has made fundamental contributions to the area of C*-algebras and to the field of noncommutative geometry in the sense of Alain Connes. He initiated the analysis of the structure of simple C*-algebras and introduced new methods and examples, including the Cuntz algebras and the Cuntz semigroup. He was one of the first to apply K-theory to noncommutative operator algebras and contributed to the development of that theory. In collaboration with Daniel Quillen, he developed a new approach to cyclic cohomology and proved the excision property of periodic cyclic theory. In recent years, he has been working mainly on C*-algebras that are related to structures from number theory.

Joachim Cuntz had dozens of PhD students and research assistants, many of which are professors in mathematics today. Among them are:
 * Xin Li (PhD 2010, professor of mathematics at the University of Glasgow)
 * Ralf Meyer (PhD 1999, professor of mathematics at the University of Göttingen)
 * Andreas Thom (PhD 2003, professor of geometry at the TU Dresden)
 * Christian Voigt (PhD 2003, professor of mathematics at the University of Glasgow)
 * Moritz Weber (PhD 2011, junior professor of mathematics at Saarland University)
 * Wilhelm Winter (PhD 2000, professor of mathematics at the University of Münster)
 * Joachim Zacharias (PhD 1996, professor of mathematics at the University of Glasgow)
