I'm a postdoc in the cryptographic engineering group led by Peter Schwabe at MPI-SP. My work concerns vulnerabilites and attacks arising from the post-quantum migration effort. This includes, but is not limited to, side-channel and fault attacks on lattice-based schemes.

I obtained my Master's of Mathematics from the University of Munich in 2020. During my Master's I focused on algebraic number theory and algebraic geometry. From 2014 to 2020, I was a working student at Infineon; in my last two years as a working student, I was supervised by Thomas Pöppelmann. In 2024, I obtained my PhD from Universität der Bundeswehr in cooperation with Infineon Technologies supervised by Gabi Dreo, Thomas Pöppelmann, and Peter Pessl. My committee consisted of Gabi Dreo, Mark Manulis, Eirini Ntoutsi, Christof Paar, and Arno Wacker.
