I am Professor and ARC Future Fellow in the Discrete Mathematics Research Group of the School of Mathematical Sciences at Monash University in Melbourne, Australia. I am the Deputy Director of the Mathematical Research Institute MATRIX and President of the Combinatorial Mathematics Society of Australasia.

My research interests lie in discrete mathematics and theoretical computer science, especially structural graph theory, extremal graph theory, geometric graph theory, graph colouring, graph drawing, and combinatorial geometry. Here are a few of my favourite open problems.
