Research Interests
- Finite geometries and linear codes.
Geometric structures (such as caps and blocking sets) in finite Galois geometries PG(n,q). Applications in digital communication (error-correcting codes) and in statistical experimental design. Algebraic coding theory (finite fields, exponential sums). - Combinatorial enumeration.
Generating functions. Counting lattice points in polytopes and applications to enumeration of various combinatorial structures. - Steganography (science of information hiding).
Steganography based on linear covering codes. Average distance to code - the numerical invariant that measures the appropriateness of a code for the steganography application. Classification of optimal codes with respect to this invariant. Connections to graph colouring problems (domatically full graphs). - Computation
Computational aspects of the topics listed above. Isomorph-free generation of combinatorial structures. Constructing structures with prescribed automorphism groups.
