Research Interests

I am a member of the Optimisation and Logistics Group at the University of Adelaide.

My research interests include program optimisation, rewriting, genetic-programming (GP) - especially the discovery of recurrences and search-based-software-engineering. I am currently supervising projects in evolutionary art and in applications of search based software engineering to energy conservation and monitoring in mobile platforms. I have also supervised successful projects in the evolution of control algorithms for robots, the evolution of three-dimensional geological models, and the synthesis and optimisation of artificial water distribution networks, and using background optimisation to improve the performance of instruction set simulators (ISS)'s.

I also have a strong interest the teaching of problem-solving skills in Computer Science curricula. In particular the learning of problem-solving skills through deliberate practice. I am a member of the Education Research Group of Adelaide (ERGA). I am one of the holders of a Google Research Award to introduce a problem-solving curriculum into Computer Science. A little more informaton on my interests in education research can be found here.

I am one of the creators of a new second year course Problem Solving and Software Development where students solve realistic and fun algorithmic problems. The course will also have a focus building the meta-cognitive skills needed to practice effectively.
