About

Summary

I was a senior lecturer in mathematics at the University of South Wales from 1989 until my retirement in 2014. Post-retirement, I have been made a Visiting Research Fellow to continue my academic role within the University. I promote education in system dynamics and mathematical modelling, and continue to pursue collaborative research projects.

My current research uses system dynamics, mathematics and sociophysics, which I apply to the growth and decline of churches, political parties and a wide variety of other social phenomena. I frequently attend conferences and meetings in the line of my research but these could be in mathematics, physics, sociology, political science, history or religion. A good mathematical modeller has to be interested in every aspect of the world!

Employment and Education

2014 – present, Visiting Research Fellow, University of South Wales. (Emeritus Position).
1989 – 2014, Senior Lecturer in Mathematics, University of South Wales/University of Glamorgan
1982 – 1989, Lecturer in Mathematics, Napier Polytechnic, Edinburgh.
1979 – 1982, Post Doctoral Research Assistant, University of Glasgow.
1978 – 1979, Lecturer in Mathematics, Accrington and Rossendale College, Lancashire.
1978, PhD Applied Mathematics, Queen Mary College, University of London.
1975, BSc Astrophysics, Queen Mary College, University of London.

Experience

I studied at Queen Mary College, University of London, where I graduated with a BSc in Astrophysics and subsequently a PhD in general relativity and gravitation. Following that I conducted postdoctoral work at Glasgow University in solar physics and became part of the NASA solar maximum mission programme.

In 1982 I joined Napier Polytechnic in Edinburgh continuing my research on solar physics and teaching mathematical modelling. In 1989 I joined the University of Glamorgan as a senior lecturer in mathematical modelling and software engineering, specialising in formal methods. Throughout the 1990s I developed a number of programming courses in Ada, C++ and the functional programming languages SML and Haskell. I conducted research in formal methods and the automated generation of computer code from the Z specification language.

Since 2000 I have concentrated exclusively on mathematical modelling in the social sciences, using system dynamics, nonlinear analysis and agent-based modelling. I have successfully supervised five research students to PhD, and one to MPhil. I taught a final year module in system dynamics for 14 years as part of BSc Mathematics. In addition I taught mathematical and agent based modelling.
