Prof. Dr. rer. nat. Oliver Waldhorst

Vita

Oliver P. Waldhorst received the degrees of Diplom-Informatiker in 2000 and Dr. rer. nat. in 2005, both from the University of Dortmund. He habilitated at the Faculty of Computer Science of the Karlsruhe Institute of Technology (KIT) in February 2011. 

Oliver Waldhorst represents the field Computer and Communication Networks at the Faculty of Computer Science and Business Information Systems since September 2016. Previously, he developed communication architectures in the area of Connected Car for Daimler AG (September 2013 - August 2016) and conducted research at KIT (September 2006 - August 2013). There, he led a junior research group from August 2007 to September 2011, which was financed by funds from the Excellence Initiative as well as external funding. During his PhD he worked as a research assistant at the University of Dortmund (April 2000 - December 2005) and after successful completion as a research assistant at the University of Leipzig (January 2006 - August 2006). From September 2009 to February 2010, he visited the University of Toronto as a Visiting Researcher in the group of Prof. Jörg Liebeherr. From April 2011 to March 2012, he substituted Prof. Andreas Mitschele-Thiel as Chair (W3) at the TU Ilmenau.
