and international scientific academies and associations. A. Erman Tekkaya is "Editor-in-Chief" of the Journal of Materials Processing Technology of Elsevier for 7 years. According to Scopus, his h-factor currently is 20 and the number of citations to his publications is 1600.

Prof. Dr.-Ing. Werner Homberg

W. Homberg is a professor at the University of Paderborn since 2007 and managed the Chair of Forming and Machining Technology (LUF) in the Department of Mechanical Engineering. There he is chairman of the Commission "Strategy and Resources" and member of the Committee for Planning and Finance at the University of Paderborn. He studied mechanical engineering at the Technical University of Dortmund. After his completion of studies, he worked as a research co-worker at the Institute of Forming Technology and Lightweight Construction (IUL) in the field of sheet metal forming. In this field, he graduated with honors in the year 2000. Subsequently, he worked as a senior engineer at the IUL and was mainly responsible for the coordination of research.

Current research focus from W. Homberg is in the areas of sheet metal- and profile-forming, forming of hybrid respectively high-strength materials and also incremental forming processes. In the area of incremental sheet metal-/profile-forming, W. Homberg developed a new forming process, called friction-spinning, in the year 2009.

W. Homberg assumes the function as reviewer in the context of national and international research funding and is member of the working group of forming technology (AGU) in Germany.

Prof. Dr.-Ing. Alexander Brosius

In July 2012 Alexander Brosius became a full Professor as head of the Chair of Forming and Machining Processes (FF) at the Technische Universität Dresden (TU Dresden). He has been a CIRP Research Affiliate since 2009 and is involved in project evaluations for the DFG as an expert reviewer.

Before beginning his studies of mechanical engineering at the University of Applied Sciences in Berlin in 1993 specializing in construction, Alexander Brosius has completed a three-year vocational training as industrial tool maker at Siemens AG in Berlin. In 1997 he became a research assistant at the Chair of Construction and Manufacturing at Brandenburg University of Technology in Cottbus before joining the Chair of Forming Technology at University of Dortmund in 1998 as part of the technical staff while completing his advanced degree specializing in production technology.

In 2002 Alexander Brosius became research assistant at the Institute of Forming Technology and Lightweight Construction (IUL) at the University of Dortmund where he received his doctorate (Dr.-Ing.) with honors in 2005 for his thesis on "A Method for the Determination of Strain-Rate-Dependent Flow Curves by Means of Electromagnetic Tube Forming an Iterative Finite-Element-Analysis".

He continued his work in research at the IUL as a department manager for the group of high speed forming and joining and later as chief engineer for research. In 2011 he was awarded the title of Assistant Professor (Juniorprofessor) for "Modelling and Simulation in Forming Technology and Lightweight Construction" at the Technical University of Dortmund from where he received his call to TU Dresden in 2012.

His research interests are metal forming technologies, material characterization and simulation methodology with a special focus on hybrid processes and process chains for property oriented manufacturing.
