Curriculum Vitae

Dr. Stephan STEGLICH is director of the Business Unit Future Applications and Media (FAME) at Fraunhofer Institute for Open Communication Systems (FOKUS) in Berlin, Germany. Stephan received his M.Sc. in computer science (in 1998) and PhD (in 2003) in Computer Science from the TU Berlin. His fields of interest include, e.g., context-awareness, user-interaction, and service front-ends. In 1998 and 1999 he has worked intensively in the research area of Intelligent Mobile Agents. Since 1999 he has started research activities in the area of user-centric communication. He has been involved in a number of projects that were related to Human-Machine-Interaction, UMTS/VHE, personalization and user profiling.

Since 2010, Stephan is working the area next generation Web platform for cross-platform and cross-device applications and media - including topics like interactive media, web technologies, VR/360° video, streaming and connectedTV/HbbTV. He is managing international and national level research activities and has been an organizer and a member of program committees of several international conferences. He is actively participating in standardization activities in these research areas and gives lectures at the Berlin University of Technology (TU Berlin).
