Thorsten Strufe is professor for peer-to-peer networks at Technische Universität Darmstadt, PI of the Center of Advanced Security Research in Darmstadt (CASED) and PI of the Joint Research Centre MAKI. 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 P2P technologies. 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 visiting professor for Dependable Distributed Systems at University of Mannheim, Germany, throughout 2011.

Previously, he took a post as senior researcher at EURECOM, where he was working with Refik Molva on security with a special focus on online social networks and did a post doc at Technische Universität Ilmenau, working on resilient networking technologies.

He received the PhD degree from Technische Universitat Ilmenau in 2007, which was advised by Günter Schäfer and Dietrich Reschke, and was awarded with the ''FFK Preis fuer die beste theoretisch orientierte Dissertation'' (FFK price for the best theory oriented dissertation). His thesis deals with the construction of network-efficient overlay topologies for live multimedia streaming, and means to making them especially resilient towards both the failure of nodes and DoS attacks.
