Srdjan Capkun (Srđan Čapkun) is a Full Professor in the Department of Computer Science at ETH Zurich, where he also serves as Associate Vice President for Digital Transformation and Governance and Chair of the Zurich Information Security and Privacy Center (ZISC). Originally from Split, Croatia, he received his Dipl. Ing. degree in Electrical Engineering / Computer Science from the University of Split in 1998, and his Ph.D. in Communication Systems from EPFL in 2004. His research focuses on system and network security, with a particular emphasis on wireless security (specifically secure positioning), trusted computing, and distributed ledgers. In 2016, he was awarded an ERC Consolidator Grant and in 2026 an ERC Advanced Grant for his work on secure positioning in wireless networks. He is a Fellow of the ACM and of the IEEE. He is a co-founder of several security-focused companies, including Soverli (building sovereign smartphone architectures), Futurae, and 3db Access (a UWB secure ranging company acquired by Infineon).
