Curriculum Vitae

Since November 2021, I am a full Professor of Computer Science at the Ruhr-University Bochum (RUB) - leading the Chair of Information Security. I am also involved as a (part-time) Chief Scientific Advisor at NEC Laboratories Europe. Before joining RUB, I was working as an NEC Fellow and was leading the Security research group at NEC Labs in Germany. Prior to joining NEC Labs, I was working as a postdoctoral researcher in the Institute of Information Security of ETH Zurich, Switzerland. Since 2011, I hold a PhD degree in Computer Science from ETH Zurich.
