Info
I am a PhD candidate at the Security Engineering group under the supervision of Tim Güneysu.
In 2021 and 2022, I was additionally part of the Cyber-Physical Systems department of the German Institute for Artificial Intelligence (DFKI).
Before my PhD, I worked as Hardware Security Engineer for Kasper & Oswald in 2019.
I obtained a M.Sc. from Ruhr University in IT security and information technology in 2019 under the supervision of Timo Kasper and Christof Paar.
During my bachelor and master studies, I worked as a student trainee at Kasper & Oswald in the area of NFC security, mainly developing the ChameleonMini.
I'm part of the HAETAE submission team.
