CURRICULUM VITAE


Dieter Hogrefe is full professor (C4) for Telematics at the University of Göttingen since 2002. He graduated at Philips Exeter Academy, USA, in 1976 and studied Computer Science and Mathematics at the University of Hannover, Germany, where he graduated with PhD in 1985. From 1983 to 1986 he was with the SIEMENS research center in Munich and worked in the area of analysis of telecommunication systems. He was responsible for the protocol simulation and analysis of the CCS No. 7. Since 2003 he is director of the Institute of Computer Science. From 1996 until 2010 Prof. Hogrefe was chairman of the Technical Committee Methods for Testing and Specification at the European Telecommunication Standards Institute, ETSI. From 2011 until 2013 he was dean of the faculty of mathematics and computer science. His research activities are directed towards Computer Networks and Communication Software Engineering. He published numerous papers and two books on Internet technology, security of wireless sensor networks, analysis, simulation and testing of formally specified communication systems. Prof. Hogrefe held full professor positions at the Universities of Bern, Lübeck, and Göttingen and visiting positions at University of Dortmund, Technical University Budapest, UC Berkeley and Hamilton University. He is married to Susan Hogrefe and has four children (Christian 1989, Luise 1990, Georg 1993 and Katharina 1998).
