Before joining the University of Twente, I was a permanent researcher at SAP Security Research in Karlsruhe, Germany. There I worked in the area applied cryptography, in particular on searchable encryption and encrypted databases. I obtained my Ph.D. with distinction from the Karlsruhe Institute of Technology (KIT) in Germany.
My interests are widespread in topics that are related to security and privacy, and my research is particularly focused on data encryption during processing for data outsourcing scenarios. These research results have various real-world applications such as encrypted storage for cloud computing, privacy-preserving machine-learning and protection of biometric data.
