Role
Dr Hetherington is the Mathematics Courses Manager, overseeing the running of:
- MMath (Hons) Mathematics;
- BSc (Hons) Mathematics;
- BSc (Hons) Mathematics with Statistics;
- BSc (Hons) Financial Mathematics;
- BSc (Hons) Mathematics with Data Science;
- BSc (Hons) Computer Science and Mathematics;
- BSc (Hons) Sport Science and Mathematics;
- BSc (Hons) Mathematics and Physics.
All of the courses above are available with an optional placement year, and with a Foundation Year.
Dr Hetherington teaches Introduction to Discrete Mathematics and its Applications (level 4), Linear Algebra and its Applications (level 5), Graph Theory and Combinatorics (level 6). He also supervises BSc projects on cryptography, and graph theory, and MMath and MRes projects on graph theory.
Dr Hetherington is the University Coordinator for the British Combinatorial Committee. He is a member, for the School of Science and Technology, of the Consideration of Personal Circumstances panel, the Learning and Teaching subcommittee, and the Study Abroad Application panel, and also a member of the Physics and Mathematics departmental Peer Observation of Teaching group. Additionally, Dr Hetherington acts as chair for Request for Reconsideration panels and Academic Integrity hearings within the School of Science and Technology.
Career overview
Before joining NTU, Dr Hetherington worked:
- at the University of Nottingham in the Financial & Business Services Department (6 months);
- in secondary schools teaching Mathematics to 11-18 year olds (1 year);
- at BAE SYSTEMS in Research & Development, New Business Operational Analysis, Eurofighter Aerodynamic Loads, and Nimrod Fuel Gauging (2 years).
Research areas
Dr Hetherington's research interests are in graph theory, particularly colourings and list-colourings.
Opportunities to carry out postgraduate research towards an MRes or MPhil/PhD exist and further information may be obtained from the NTU Graduate School.
