Security Architect

Infineon Technologies


I am a Security Architect at Infineon Technologies, Munich. Before that, I was a PhD student and Postdoc in the Secure Systems group at the Institute of Applied Information Processing and Communications at Graz University of Technology . There, I performed research on implementation attacks (side channels and faults) and respective countermeasures for cryptographic primitives. In particular, I focused on implementation security of lattice-based cryptography and other quantum-secure schemes.

At Graz University of Technology, I taught the following courses.

  • Introduction to Information Security (practicals 2015 , 2016 , 2017 , 2018 )
    Undergraduate course, programming exercises teaching the basics of information security.

  • Information Security (practicals 2019 )
    Undergraduate course, programming exercises teaching the basics of information security.

  • Embedded Security (lecture and practicals 2017 , 2018 )
    Graduate course on physical implementation attacks (power analysis, fault attacks) and countermeasures.

I also supervised several master and bachelor theses on side-channel attacks and efficient implementations of cryptography.

Besides, I held tutorials on side-channel attacks at the Graz Security Week (2017, 2018, 2019).
