Urs Hengartner is a member of the Cryptography, Security, and Privacy (CrySP) research group, the Centre for Applied Cryptographic Research and the Systems and Networking Group.

He has a PhD and MS in Computer Science from Carnegie Mellon University and a Dipl. Informatik-Ing. ETH from ETH Zürich.

His research interests are in information privacy and computer and network security with a focus on security and privacy challenges that arise in the context of smartphones and mobile applications. Urs and his students develop privacy-preserving technologies for location-based services and mobile applications to protect users from having to share their personal information with service and application providers.

Urs and his students also study implicit authentication for smartphones, where a smartphone continuously authenticates its owner based on the owner's behaviour without requiring deliberate actions by the owner. He has also worked on privacy-preserving location verification technologies, genomic privacy, and end-to-end voter-verifiable voting systems.
