Ian has worked with IP technologies since 1990. He was involved with ST-II (IPv5) at the european networking center in IBM, Germany. After arriving at SICS he worked on real time transport protocols, particularly with Voice over IP. He obtained his PhD degree from KTH in 2009.
Ian was worked with probablistic and statistical methods within several different domains. This includes networking, image processing and graphical algorithms. He has applied probablistic methods to real time communication, black box analysis of telecom equipment and large data sets
He has also partial differential equations (PDE) in the modelling of flows (requests, packets, vehicles)

Opponent: Professor Henning Schulzrinne (Columbia University USA)Place: KTH, D2, Lindstedtsv. 5, 3rd floor. Abstract: Internet telephony has had a tremendous impact on how people communicate. Many now maintain contact using some form of Internet telephony. Therefore the motivation for this work has been to address the quality aspects of real-world Internet telephony for both fixed and wireless telecommunication. The focus has been on the quality aspects of voice communication, since poor...
