Julia Seiter currently works as a software architect at VEMAG Maschinenbau Gmb H in Verden, Germany. She received the Diploma degree in computer science from the University of Bremen, Germany, in 2012. In 2015, she received her Dr.-Ing. degree, also from the University of Bremen, after having been with the Group of Computer Architecture for three years. Her research was focused on the design and verification of formal system models.
Robert Wille is a Full Professor at the Johannes Kepler University Linz. He received the Diploma and Dr.-Ing. degrees in computer science from the University of Bremen, Germany, in 2006 and 2009, respectively. He was with the Group of Computer Architecture at the University of Bremen and with the German Research Center for Artificial Intelligence (DFKI). Additionally, he worked as Lecturer at the University of Applied Science in Bremen, Germany, and as visiting professor at the University of Potsdam, Germany, and the Technical University Dresden, Germany. His research interests are in the design of circuits and systems for both conventional and emerging technologies with a focus in the domain of synthesis and verification.
Rolf Drechsler is head of Cyber-Physical Systems department at the German Research Center for Artificial Intelligence (DFKI) since 2011. Furthermore, he is a Full Professor at the Institute of Computer Science, University of Bremen, since 2001. Before, he worked for the Corporate Technology Department of Siemens AG, and was with the Institute of Computer Science, Albert-Ludwig University of Freiburg/Breisgau, Germany. Rolf Drechsler received the Diploma and Dr. Phil. Nat. degrees in computer science from the Goethe-University in Frankfurt/Main, Germany, in 1992 and, respectively, 1995. Rolf Drechsler focusses in his research at DFKI and in the Group for Computer Architecture, which he is heading at the Institute of Computer Science of the University of Bremen, on the development and design of data structures and algorithms with an emphasis on circuit and system design.
