Welcome

About Me

I am a research engineer focussing on improving the security of embedded systems for different application scenarios.

My academic research for my PhD and post-doctoral studies has been carried out at the University of Luxembourg in the SEDAN group at the Interdisciplinary Centre for Security, Reliability and Trust (SnT).
