Role
Principal Lecturer – Mathematics Course Manager
Dr Hetherington is the Mathematics Course Manager, overseeing the running of BSc Mathematics, BSc Financial Mathematics, BSc Computer Science and Mathematics, and BSc Sport Science and Mathematics. He teaches Algebra 2 (year 2), and Graph Theory (year 3) which is half of a module on Advanced Topics in Pure Mathematics and supervises final year projects on coding theory, cryptography, combinatorics and graph theory.
Dr Hetherington is the University Coordinator for the British Combinatorical Committee. He is also a member of the Programme Development and Review Subcommittee and sits on School Academic Irregularity Panels.
Research areas
Dr Hetherington is a member of the Intelligent Simulation, Modelling and Networking Research Group (ISMN).
Research interests include graph theory and combinatorics, in particular colourings and list-colourings.
Opportunities to carry out postgraduate research towards an MPhil/PhD exist and further information may be obtained from the NTU Graduate School.
