Lecturer
Teaching
- CS4402 - Constraint Programming
- CS4303 - Videogames
I also supervise projects at a variety of levels across our school.
Research areas
I am a Lecturer in the AI group. My main research focus lies in Automated Planning, which is a central discipline of Artificial Intelligence. This area studies decision-making in a given environment to reach or optimise a goal. These problems are ubiquitous in industry and science, where they appear in logistics, chemistry or even network security, just to name a few. More concretely, my published work mainly lies in the intersection of Automated Planning, Constraint Satisfaction, Reformulation and applications of logic in computer science.
