Prof. Dr.-Ing. Christoph Gehlen


Materials Science and Testing​​​​​​​

Academic Career and Research Areas

Prof. Gehlen (*1966) conducts research in the field of construction materials. His research focuses, among other things, on the development of materials for large-format 3D printing in the construction industry, the development of methods for characterizing materials and components made from them and testing them with regard to a wide range of properties (including in-situ), and work aimed at describing and predicting the service life of mineral and metallic building materials as a function of exposure.

After studying chemistry and mineralogy in Bonn, he graduated in civil engineering from RWTH Aachen University in 1995. Subsequently, he obtained his doctorate at the RWTH Aachen (2000). He then founded an internationally active engineering firm in Munich, together with two partners. After being appointed to a chair at the University of Stuttgart (spring 2006, chair "Materials in Civil Engineering"), he moved to the TUM chair "Materials Science and Testing" in the fall of 2008. From 2012 to 2016, Professor Gehlen was Dean of Studies, from 2016 to 2021 Dean of the Faculty of Engineering Bau Geo Umwelt (BGU), and since October 2021 he has been the founding Dean of the new TUM School of Engineering and Design (ED).
