Current research project/students
- Graph reconstruction of polytopes: This project is about reconstructing the combinatorial structure of a polytope from its graph or dual graph, and if a reconstruction is possible, how efficiently it can be performed. The combinatorial structure of polytopes is given by partially ordering the polytope faces by the inclusion relation.
- Degree-diameter problem: This project aims to prove existence or otherwise of large graphs subject to constraints to the maximum degree, diameter and the graph class. Graph classes of interest include Cayley graphs and graphs embedded on surfaces. Students: Associated Supervisor of a completed PhD thesis and of an ongoing PhD student: Both students have been enrolled at the University of Newcastle.
- Applications of Graph Theory to Sport Scheduling: This project applies graph theory concepts and methodology to sport scheduling.
- Students: Supervisor of an honours thesis.
