Christoph Leyens

from Wikipedia, the free encyclopedia

Christoph Leyens (* 1967 in Oldenburg ) is a German engineer, materials scientist and university professor. He has headed the Institute for Materials Science at TU Dresden since 2010 and has also been the institute director of Fraunhofer IWS Dresden since 2018 .

Life

Christoph Leyens studied metallurgy and materials engineering at RWTH Aachen University from 1988 to 1993 . After receiving his diploma, he first worked as a doctoral student, then as a group leader and later as acting institute director at the Institute for Materials Research of the German Aerospace Center (DLR) in Cologne from 1993 to 2004. 1997 Leyens worked at RWTH Aachen University to Dr.-Ing. PhD. The topic of his dissertation was the development of anti-oxidation coatings for titanium alloys. From 1998 to 1999 the DLR initially worked for 12 months at Oak Ridge National Laboratory , Tennessee, USA, and then for a further 6 months at Lawrence Berkeley National Laboratory , California, USA for research stays in the field of high-temperature protective coatings for stationary gas turbines and Aircraft engines seconded. In 2005, he completed his habilitation at RWTH Aachen University in the field of aerospace materials.

Before that, in 2004 he accepted a professorship for metallurgy and materials engineering at the Brandenburg Technical University (BTU) Cottbus . There he was also managing partner of Panta Rhei gGmbH - Research Center for Lightweight Construction Materials, Cottbus. From 2007 to 2009 Leyens was Vice President for Research, Development and Innovation at the BTU Cottbus.

In 2009, Christoph Leyens accepted the professorship for materials technology at the Technical University of Dresden , where he has also been director of the Institute for Materials Science since 2010. In connection with his professorship at the TU Dresden, he has held various management positions at the Fraunhofer Institute for Material and Beam Technology Dresden (IWS) since 2009 ; Leyens has been the sole director of the institute since 2018.

Christoph Leyens' research focuses on the areas of lightweight metallic and high-temperature materials, intermetallic materials, functional materials, surface technology, laser material processing and additive manufacturing. His research work is documented in over 200 texts and 4 books.

Leyens is a member of various professional associations ( DGM , VDI , WAW) and is currently the spokesman for the thematic network materials science and materials technology at acatech - German Academy of Science and Engineering. In addition, he is CEO of AGENT-3D eV and coordinates the major project AGENT-3D: Additive-Generative Manufacturing within the framework of the BMBF funding program Zwanzig20.
