Biography

At high school I was lucky to be benefit from the hard work of very fine teachers. They encouraged my wide interests in mathematics, physics and history from a young age. Later, I spent four years at Oxford University studying Mathematics: three years for my BA, then a year for my MSc in Mathematical Modelling and Numerical Analysis. Afterwards I was employed in industry, devising predictive methods and computer programs for a diesel manufacturer. I moved on to Bristol University, to be employed as a research associate. There I worked for my PhD in breaking waves, and in postdoctoral research, all supervised by the late Professor D.Howell Peregrine. In Nov. 1992 I left Bristol to become a lecturer, now a senior lecturer, at UEA.

Key Research Interests

Applied Mathematics

Fluid Mechanics

Free surface flows and water waves.


My research is in the fluid mechanics of unsteady water waves, breaking waves and free surfaces. I have an ongoing interest in violent flows, such as splashes and liquid jets. One reason for trying to solve free boundary problems of this type is to account for the extremely high pressures and forces on structures struck by water waves, such as ships and harbour walls. The next time you are at the beach watching the waves, notice the jet or arch of water made by an overturning wave. It contains water whose acceleration can exceed 4g. When waves impact cliffs and seawalls the water undergoes even higher acceleration. Such impacts are an especially vigorous class of violent flow. Examples include (i) a sea wave breaking onto a vertical harbour wall, and (ii) a ship plunging into an oncoming series of waves (a `head-sea'). PhD students with my supervision have worked in these areas, e.g.  modelling the displacement of shingle and boulders on beaches struck by waves; another project was on the most highly accelerated liquid jets. I also have an interest in the safe landing of aircraft onto water (ditching) in recent PhD and postdoc projects. An on-going shared project, with a Visiting Fellow, is wave-impact forces on open structures, e.g. offshore wind turbines.

Teaching Interests

For undergraduates my lectures and project supervisions (maths and science students) embrace fluid mechanics (years 2,3,4) and the history of mathematics (year 3), particularly tracing ideas in the differential and integral calculus since the ancient Greeks. My lectures include a stream `Maths for Scientists' for years 1-2: complex numbers and solving differential equations, integration and later elementary fluid mechanics. These are the elements for modelling natural processes. I have also taught basic maths to Foundation Year students, and advanced topics to postgraduates, e.g. in research skills and nonlinear waves. Final-year MMath projects and BSc projects include  modelling such things as an oscillating lit candle, a person trying to keep warm (or cool), the effect of a wind-gust on a tree, and how a thrown stone can bounce repeatedly on a lake’s surface.
