A Short CV

Dr. Christian Hoene is a postdoc at the “Computer Networks and Internet” group at the University of Tübingen, Germany. He is a researcher covering the areas of Internet based voice communication, wireless transmissions, location tracking, metering, accounting, and charging. Christian has studied at Technical University of Berlin in the TKN Group. He is the author of about 30 publications, 1 ITU standard contribution, and has received one best paper award. Herr Hoene was also awarded in 2000 with Erwin Stephan Prize for passing his studies of computer engineering at the TU-Berlin with distinction. In 2001, he was a visiting scholar at the COMET Group of Prof. Campbell, Columbia University, New York. In 2005 he finished his Ph.D. studies on voice over WLAN also with distinction. He is supported within the elite programme for postdocs, which is funded by the Landesstiftung Baden-Württemberg. Since April 2008 he has been in charge of the main lectures because the chair of the Computer Networks and Internet group is vacant.

His scientific merits are affirmed by about 340 citations and a Hirsch-factor of 9 according to the comprehensive data base of Google Scholar. The results of his work have influenced the standardization of ITU-T Study Group 12 (appendix to ITU G.107), IEEE 802.11v working group and Internet Engineering Task Force (IETF, an IETF draft).

He is in the TPC of the IEEE workshop on Bandwidth on Demand 2008, the IEEE conferences CCNC 2010, NEW2AN 2009, ICC 2008, ICC 2009 and ICC 2010 and on ACM CoNEXT 2008 (Shadow) and a reviewer for ICC, Globecom, VTC, IEEE/ACM Transactions on Networking, IEEE Transactions on Wireless Communications, IEEE Transactions on Network and Service Management, IEEE Transactions on Industrial Informatics, Elsevier Ad Hoc Networks Journal, Elsevier Computer Networks Journal, Elsevier Computer Communications Journal and other conferences and journals.

Dr. Hoene is a member of IEEE Comsoc, GI, VDI and AES.
