Dr. Stefan J. Eder is a principal scientist at the Austrian Excellence Center for Tribology (AC2T research GmbH), which employs some 120 scientists of various backgrounds and is one of the world's largest private research service providers in tribology. He is also the group leader of the nanoscopic modeling activities in the tribology unit of Carsten Gachot at TU Wien (Vienna). His main research interests include the computational analysis of the near-surface microstructural development in polycrystalline alloys under tribological load as well as the reactive simulation of tribochemical phenomena. Dr. Eder has been active in the field of tribology since 2007, received his PhD in physics from TU Wien in 2012 and his venia docendi (habilitation) in the field of computational materials tribology in 2023. He has been an academic visitor at the tribology groups of Prof. Ashlie Martini at the University of California Merced (UCM), as well as Prof. Daniele Dini at Imperial College, London (UK), and he also maintains an active scientific collaboration with the Karlsruhe Institute of Technology, among others. He has authored some 60 papers in peer-reviewed journals and contributed to around 100 conferences, including more than 20 invited/plenary talks. He has been involved in winning national and international research grants (FFG, FET-Open, Horizon2020), serves on several editorial boards, and is the organizer of the Vienna Virtual Materials Tribology Workshop (ViViMaT) on YouTube (175+ subscribers).
