Prof. Jürgen Gegner studied Physics at the University of Erlangen-Nuremberg and completed his first degree (“Dipl.-Phys.”) in 1989 with a diploma thesis on deuteron-deuteron scattering. He graduated his doctoral studies in Materials Science (“Dr. rer. nat.”) at the University of Stuttgart, where he defended his dissertation on interfacial oxygen segregation in 1994 at the Max Planck Institute for Metals Research. After postdoctoral research on ceramics and aluminum alloys at the Max Planck Institute for Microstructure Physics in Halle and the Institute of Applied Mechanics at the University of Erlangen-Nuremberg, respectively, he joined the Loctite Global Engineering Center at Garching near Munich in 1999 as Senior Engineer. Since 2000 he has been working for SKF in Schweinfurt, from 2005 as manager of the Material Physics laboratory. He defended his postdoctoral degree in Materials Science (venia legendi, “Dr. rer. nat. habil.”) with a habilitation thesis on solid state diffusion and a lecture on adhesive bonding at the University of Siegen in 2005, where he was promoted to Adjunct Professor in 2012. In 2008, he was announced as Visiting Professor of Materials Research at Ariel University in Israel. Since 2007, he is head of the German Research Committee for Residual Stresses. His main fields of work are material use with a focus on rolling contact tribology, surface engineering, heat treatment, materials development, characterization and testing, microstructure analysis, mechanistic modeling and numerical simulation. He published 4 books and more than 150 papers, is inventor of 19 patents and committee member of leading international conferences, at which he gave 9 invited plenary and keynote lectures.
