Research Interests

My research interests include theoretical and applied aspects of coding theory and cryptography as well as topics in algebra, ring theory, module theory and computational algebra.
My current research focuses on investigating algebraic properties and parameters of quasi-cyclic codes. Special emphasis is devoted to the subfamilies of quasi-cyclic low density parity check codes (QC-LDPC codes) and quasi-cyclic moderate density parity check codes (QC-MDPC codes), where my focus is to discover novel algebraic constructions, decoding algorithms, lower minimum distance bounds and their impact in Code-based cryptography. QC-LDPC codes represent the current state of the art in error-correction, while QC-MDPC codes lie in the heart of the code-based cryptosystems BIKE and HQC, which are finalists in the NIST Post-Quantum Cryptography Standardization. In addition to these topics, I am also interested on Symbolic Computation, I am a member of the group that is developing a Coding Theory package for Macaulay2. I am also developing MAGMA code for classical topics in Coding Theory.
