Research overview

My research is in optimisation, i.e., finding the best solution to problems that have a huge (possibly infinite) number of solutions.  Optimisation is an inter-disciplinary subject, lying at the interface between Operational Research, Computer Science, Applied Mathematics and Engineering.

I concentrate mainly on methods for solving optimisation problems to proven optimality, rather than heuristic methods.  I have a particular interest in combinatorial optimisation problems, i.e., problems in which variables are restricted to take integer (whole-number) values.

PhD supervision

Most of my PhD students work on exact solution algorithms for NP-hard optimisation problems. Candidates need to be comfortable with mathematics. Experience in programming (in, e.g., C, Julia, MatLab or Python) is highly desirable, as is basic knowledge of linear algebra and graph theory.
