About me

I am a postdoctoral researcher at the Technical University of Munich in the group of Professor Antonia Wachter-Zeh where I will work on coding theory for DNA storage. Before, I obtained my PhD from the University of Zurich under the supervision of Professor Joachim Rosenthal while I was a full-time researcher at the German Aerospace Center (DLR) in the Quantum-Resistant Cryptography Group of Dr. Hannes Bartz.

Coding theory represents the intersection of all my research interests which include (but are not limited to) probability theory, number theory, combinatorics, algebra and cryptography.

News

I am happy to share that just started my first Post-Doc position at the Technical University of Munich under the supervision of Professor Antonia Wachter-Zeh. I am looking forward to the new milestone and the exciting projects.

In April 2024, I successfully defended my PhD thesis entitled "Analysis and Decoding of Linear Lee-Metric Codes with Application to Code-Based Cryptography" at the University of Zurich. I am grateful for the opportunity I had and I thank my advisors Joachim Rosenthal, Hannes Bartz and Gianluigi Liva for guiding me through this adventure! Watch me wearing my beautifully made doctoral hat!!



Most recently, together with Hugo Sauerbier Couvée and Thomas Jerkovits we submitted a work on bounds on the spheres in the sum-rank metric. Have a look here.

In Collaboration with Hannes Bartz, Gianluigi Liva and Joachim Rosenthal, I just published a preprint on LDPC codes over integer residue rings endowed with the Lee metric. We analyzed their decoding performance over two channel models and derived bounds based on their average weight enumerator.
