Research Interests

My research interests and activities lie at the interface of Computer Science, Artificial Intelligence and Operational Research:

Intelligent decision support systems, data science, search and optimization (combinatorial optimisation, constraint optimisation, multi-modal optimisation and multi-objective optimisation) using heuristics, local search, hyper-heuristics, meta-heuristics (in particular memetic algorithms, particle swarm optimisation), hybrid approaches and their theoretical foundations.

Modelling of and applications to the real world and theoretical problems (course timetabling, exam timetabling, presentation (jury) timetabling, room arrangement, employee scheduling, stock cutting, strip packing, SAT, 0-1 multiple knapsack problem, TSP) that are at the intersection of computer science and operational research, including grouping (data clustering, graph colouring and bin packing) problems.

Minor interest in computational geometry, pattern recognition, image processing, intelligent user-interfaces, natural language processing and game playing.
