Prof. Dr. mont. Christoph Kirchlechner

Christoph Kirchlechner studied material science and received his PhD at the University of Leoben in Austria. Subsequently, he held an Assistant Professor position at the University of Leoben (2012-1018) and was a group leader for in situ Nano- and Micromechanics at the Max-Planck-Institut für Eisenforschung in Düsseldorf, Germany (2013-2020), with an interim stay at the UT Knoxville and the Oak Ridge National Lab with Prof. George M. Pharr. Since 2020, he is head of the Institute for Applied Materials – Materials- and Biomechanics (IAM-WBM) at the Karlsruhe Institute of Technology. His research focusses on a mechanism-based understanding of plasticity, fatigue and fracture at the micron scale, particularly at single interfaces. For this purpose, he is using electron microscopy as well as advanced synchrotron techniques. He was awarded with a promotion sub auspiciis praesidentis rei publicae (Austrian President) and a Heinz Maier-Leibnitz prize (German Research Foundation).
