Michael Schwarz

I am an infosec Ph.D. student at Graz University of Technology. I am part of the Secure Systems group at the Institute of Applied Information Processing and Communications.
As part of the university's CTF team I frequently participate in CTFs.
During the semester I teach Systems Programming, Operating Systems and Security Aspects in Software Development.
