Dr.-Ing. Martin Florian

Research Group Lead

Martin Florian received his doctorate in computer science from the Karlsruhe Institute of Technology (KIT) in 2016. From 2012 to 2017, as part of the Institute of Telematics at KIT, he conducted research on privacy in smart traffic, peer-to-peer systems and Bitcoin. On an abstract level, he explored the question of how the protection of user privacy can be reconciled with the realization of robust and secure system functionality, as well as the question to what extent central trust anchors can be made obsolete through innovative peer-to-peer approaches.

From April 2017 to February 2018 he was part of Bundesdruckerei Innovations, where he worked on solutions for data protection, data analysis and identity management, as well as on blockchain-inspired distributed systems.

Since March 2018 he is heading the Weizenbaum research group "Trust in Distributed Environments".
