Thomas Lengauer, born 1952, studied Mathematics and Informatics at Berlin and Stanford. After a brief stay at the Bell Laboratories, he held various academic positions at the universities of Saarbruecken, Paderborn, and Bonn. From 1992 to 2001, he headed the Institue for Algorithms and Scientific Computing at the GBM in Sankt Augustin (Germany). Since 2001, he is director at the Max-Planck-Institute for Informatics in Saarbruecken (Germany).Professor Lengauer has recently been awarded the Konrad-Zuse-Medal, the highest honor of the German Informatics Society.
