Thorsten Strufe is professor for Privacy and IT-Security at Technische Universität Dresden, vice speaker of the German Cluster of Excellence on Tactile Internet with human-in-the-loop CeTI, PI of the Joint Research Centre HAEC, PI of the Graduate School "RoSI", and PI of the 5G-Lab Germany. His research interests lie in the areas of large scale distributed systems and social networking services, with an emphasis on privacy and resilience. Recently, he has focused on studying user behavior and security in online social networks and possibilities to provide privacy-preserving and secure social networking services, partially through decentralization. One of the challenges driving him is the question, how competitive online and mobile services can be created without comprehensive collection of personal information, which hence respect the privacy of their users. He was appointed professor for for Peer-to-Peer networks at Technische Universität Darmstadt, Germany, from 2009 to 2014, and visiting professor for Dependable Distributed Systems at University of Mannheim, Germany, throughout 2011.
