Daniel Gruss

I'm an infosec researcher working as a postdoc in the Secure Systems group at the Graz University of Technology, Institute of Applied Information Processing and Communications (see my profile there), where I also obtained my PhD in June 2017. In summer 2016 I've been an intern at Microsoft Research Cambridge. In my research I explore software-based microarchitectural attacks and operating system features.

I teach undergraduate courses (Operating Systems, System-Level Programming) and graduate courses (Embedded Security, Security Aspects in Software Development).
