Biography

Since May 2018, I am a postdoctoral researcher in the Coding for Communications and Data Storage (COD) group at the Technical University of Munich (TUM), where I am working on algebraic coding theory and its applications in network coding and cryptography.

From January 2014 to April 2018, I was a research assistant and PhD student at the Institute of Communications Engineering, Ulm University, where I was advised by Martin Bossert. I defended my PhD thesis with the title "Construction and Decoding of Evaluation Codes in Hamming and Rank Metric" in June 2018.

I obtained a B.Sc. in electrical engineering from Ulm University (2009-2012), was an exchange student at the University of Toronto, Canada, for two semesters (2012-2013), and received a B.Sc. in mathematics from Ulm University (2013-2016).

Research

I am interested in algebraic coding theory, its related mathematical methods, and its applications.

Concatenated Codes for Error Correction in DNA Storage

Concatenated Codes for Error Correction in DNA Storage

Beschreibung

Encoding information into synthetic DNA is a novel approach for data storage. Due to its natural robustness and size in molecular dimensions, it can be used for long-term and very high-density archiving of data. Since the DNA molecules can be corrupted by thermal processes and the writing/reading process of DNA molecules can be faulty, it is necessary to encode the data using error-correcting codes. Due to the channel model concatenated codes are a suitable candidate for efficient error correction.

The student will analyze existing schemes for error correction in DNA storage based on concatenated codes and develop improved methods using soft information in the outer code, unequal error protection and list recovery. The improvements will be analyzed anlytically and by simulations.

Decoding of Interleaved Codes

Decoding of Interleaved Codes

Stichworte:
Coding Theory, Interleaved Codes, Code-based Cryptography

Beschreibung

Interleaving is a decoding method that allows correcting burst errors beyond the unique decoding radius with reasonable complexity. It is already in use for improving the performance of Reed-Solomon codes in storage applications such as CD and DVD . However, for many codes it is unclear how to use interleaving to decode up to their designed minimum distance. This work will focus on codes with application to security, i.e., code-based cryptography. Here interleaving has the potential to increase the security level for a given key size.
