Volker Hilt

Stuttgart, Germany
Head of Autonomous Software Systems Research


Ph.D. (Dr. rer. nat.) in Computer Science
University of Mannheim, Germany
June 2001

M.S. in Commercial Information Technology (Diplom Wirtschaftsinformatiker)
University of Mannheim, Germany
December 1996


Dr. Volker Hilt is leading the Autonomous Software Systems Research group at Nokia Bell Labs. The group focuses on creating technologies for automating large-scale software systems that makes them simple to run and perform optimally. Dr. Hilt received his M.S. in Commercial Information Technologies in 1996 and his Ph.D. in Computer Science in 2001 both from the University of Mannheim in Germany. He joined Bell Labs in Holmdel, NJ in 2002 and moved to Stuttgart, Germany in 2012.

His field of research is computer networking where he has made contributions in the areas of cloud computing, distributed multimedia systems, content distribution networks, peer-to-peer applications and the Session Initiation Protocol (SIP). He has designed the overload control mechanism for SIP, which has become a key part of todays telecommunication systems. Dr. Hilt has published over 60 papers and co-authored more than 15 Internet drafts and RFCs.
