Since August 2005 I am working at Tekelec in the area of IP signaling and IMS. Prior to this, I worked for 10 years at the Fraunhofer Fokus as student, researcher and head of departement. During this time I worked on various research projects relating to QoS, multimedia comunication, VoIP and security. I was also co-founder of the iptel.org project which has resulted in the developement of the widely used SIP Express Router and the foundation of iptelorg.com which was later aquired by Tekelec. I have gradutaed from the Technical University of Berlin in 1995 and finished by PhD there in 2000 |
