Portrait von Prof. Dr. Ludwig Staiger

Prof. Dr. Ludwig Staiger (*1948, Jena) studied Mathematics at the Friedrich-Schiller-Universität Jena   (Diplom 1970, Promotion 1977, Habilitation 1979). From 1970 till 1973 he had a postgraduate study at the Yerevan State University (with Prof. R. R. Varshamov). From 1973 till 1982 he was staff member at the mathematical department  of the Friedrich-Schiller-Universität Jena.
From 1982 till 1989 he was a scientific researcher  at the Academy of Sciences in Berlin (East): at the Cental Institute of Cybernetics and Information Processes and at the Karl-Weierstraß-Institute of Mathematics.
In 1989 he was Associate Professor for Algebra at the Technical University Otto-von-Guericke Magdeburg.
In the years 1990 till 1995 he was visiting professor at the RWTH Aachen, the universities Dortmund, Siegen, Cottbus and again at the RWTH Aachen, and was a guest professor at the TU Wien.
Since April 1, 1995 he is full professor for Theoretical Computer Science at the Martin-Luther-Universität Halle-Wittenberg.
From September 2000 till August 2006 he was the head of the Department for Mathematics and Computer Scinece.

Dr. Staiger`s Erdös number    is 2.

Dr. Staiger is external researcher of the CDMTCS.

He is a member of the Advisory Board of the Journal of Automata, Languages and Combinatorics    and of the managing commmittee of the Georg Cantor Association.
