    Scientific Career:

    Erik Bitzek studied physics at the University Stuttgart where he received his Diploma (Dipl. Phys.) with distinction in 2000. After starting his PhD in the group of Prof. Eduard Arzt at the Max Planck Institute for Metals Research (now MPI for Intelligent Systems) in Stuttgart, he moved in 2002 with his advisor, Prof. Peter Gumbsch, to the newly founded Institut für Zuverlässigkeit von Bauteilen und Systemen (now IAM-CMS) at the technical university Karlsruhe (now KIT), from where he obtained his doctorate degree (Dr.-Ing.) with distinction in 2006. During his first Postdoc in the group of Prof. Helena van Swygenhoven at the Paul Scherrer Institute in Switzerland he was also visiting scientist at the Ohio State University, USA, in the groups of Prof. Peter Anderson and Prof. Yunzhi Wang. His second Postdoc with Prof. Ju Li brought him to the University of Pennsylvania, USA, to which he stayed connected as visiting professor after being appointed at the Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) in 2009 as assistant professor (“Juniorprofessor”). Since winter 2015 he is full professor at the Department of Materials Science and Engineering, Institute I. Since 2013 he is furthermore Chair of the international Elite Master’s Programme “Advanced Materials and Processes (MAP)”.
    Prof. Bitzek is 2. speaker of the research training group GRK2423 “Fracture across Scales” and member of the board of the research training group GRK1896 “In-Situ Microscopy with Electrons, X-rays and Scanning Probes” at FAU.

    Erik Bitzek serves the scientific community amongst others as member of the editorial board of the Journal of the Mechanical Behavior of Materials and the Journal of Molecular Modeling, as coordinator of the German part of the International Research Network (GDRI) “Mechanics of Nano-Objects” (MECANO), member of the Executive Committee of the conference series “Dislocations”, and leader of the working group 3D Materials Data Science of the German Materials Research Society (DGM). He is also member of the European Materials Modeling Council (EMMC), the European Materials Characterization Council (EMCC) and expert on “Advanced Materials and Nanotechnology (AM&N) Modelling, Simulation and Design” for the LEIT programme of the European Commission. He furthermore serves as reviewer for the ERC, various organizations in Germany, Austria, Israel, Canada and the US, and for top-ranked journals in materials science and physics. He also has organized and co-organized more than 15 national and international workshops and symposia.

    He is author and co-author of more than 45 publications in international peer-reviewed journals, of one patent application and has given invited presentation at more than 50 international conferences, workshops and seminars. In 2008 his work was designated as “Outstanding Research by Promising Young Researchers in Mechanics and Materials” by the Japanese Society of Mechanical Engineers, in 2009 he was awarded the Best Poster Award at the Gordon Research Conference on Physical Metallurgy and obtained in 2013 the starting grant of the Cluster of Excellence Engineering of Advanced Materials (EAM).
    In 2016 he was awarded an ERC Consolidator Grant for his project Microscopic Origins of Fracture Toughness (microKIc).
