Simeon Ball

Simeon Ball is a Senior Lecturer (Profesor Agregat) at the Universitat Politècnica de Catalunya (UPC), affiliated with the Department of Mathematics and the School of Telecommunication and Aerospace Engineering. His research focuses on classical and quantum error-correcting codes, finite geometries, semifields, and graph theory, with a strong emphasis on applying geometrical and linear algebra methods. He has held academic positions at UPC since 2007, previously holding research roles at institutions like the Technical University of Eindhoven and Queen Mary College, University of London.

Ball holds a PhD from the University of Sussex (1994) and a Bachelor of Arts in Mathematics from the University of Cambridge (1989). He has authored three influential books, including Finite Geometry and Combinatorial Applications (2015) and A Course in Combinatorics and Graphs (2024). His work has been supported by grants from the Spanish Ministry of Science, including projects on combinatorics and applications.

Ball actively supervises doctoral students and advises master’s theses, focusing on topics like quantum LDPC codes, Hilbert spaces, and geometric quasi-cyclic codes. He teaches courses on quantum computation, linear algebra, and coding theory. Ball is also an editorial board member of the Journal of Geometry and Journal of Combinatorial Theory, Series A.

His research contributions span over 150 publications, including seminal works on MDS codes, finite geometries, and quantum error correction. Key achievements include proving the MDS conjecture over prime fields and developing geometric approaches to stabilizer codes.
