Georg Rill has been a researcher and an educator for more than thirty years. He is professor at the OTH Regensburg, Germany.His first book, entitled Simulation von Kraftfahrzeugen, was published in 1994. Recently, he contributed the part Multibody Systems and Simulation Techniques to the book Vehicle Dynamics of Modern Passenger Cars.

Abel Arieta Castro is a research engineer at EFS, a major supplier of the automotive industry. He developed a robust and fault tolerant integrated control system to improve the stability of road vehicles in critical driving scenarios during his PhD. As a post-doc he spend several months at the OTH, where he deepened his knowledge on vehicle dynamics and tire modeling.
