Dr Peter Gregory

I gained my PhD from the University of Strathclyde in Glasgow in 2008. At Strathclyde I worked in the Strathclyde Planning Group, a world-leading planning research group. My thesis was titled “Structure in Satisfiability”, and covered various topics in Planning and Boolean Satisfiability. After that, I worked on two EPSRC-funded post-doctoral positions at Strathclyde. The first of these was titled Meta-CSP for Optimal Planning. The second was called Modelling in Planning.

I left Strathclyde in November 2011 to join the University of Huddersfield as a research fellow. At Huddersfield, I work within the ARTFORM group, researching various areas of planning.

I am interested in a broad range of topics in combinatorial search. My key areas of interest are Planning, Constraint Programming and Timetabling.

My current research involves planning using constraint satisfaction techniques, knowledge engineering in planning, rich modelling languages for planning, path planning techniques and abstractions in both planning and timetabling.
