Personal profile
Research overview
My main research interest is Constraint Programming (CP). I have been working on the automated constraint modelling tool Conjure and on high-level modelling/reformulation research through Conjure. For more details about Conjure see GitHub: https://github.com/conjure-cp
I am also very interested in applications of CP to specific problems. I have worked on applications in areas including Computer Science (data mining, cloud computing, network science), Mathematics, Economics and Logistics.
I am interested in a variety of other things including programming languages research (especially functional programming), data linkage, algorithm selection & configuration, and the intersection of ML/statistics and CP.

Teaching activity
I taught some of our core CS modules for first and second years:
- CS1003 - Programming with Data
- CS2003 - The Internet and the Web: Concepts and Programming
And honours & post-graduate level modules:
- CS4402 - Constraint Programming
- CS5929 - Discrete Optimisation
- CS4303 - Video Games
- CS5001 - Object-Oriented Modelling, Design and Programming
I enjoy supervising students at various levels including undergraduate projects, masters dissertations, and PhD students. I am also leading a VIP (Vertically Integrated Projects) called "Artificial Intelligence for Decision Making". VIPs are ongoing projects that can be taken by students for several semesters. See the general VIP webpage for more details.
