ResearchMy educational research currently focuses on using computer algebra systems for assessment of mathematics. A practical outcome of this is the STACK computer aided assessment system. My interest in mathematical notation resulted in a project student, Alex Billingsley, creating the DragMath project.
My applied mathematics research investigates dynamical systems and mathematical control systems.
In 2006 I was awarded a University of Birmingham Teaching Fellowship and a National Teaching Fellowship.
Details of my work are available in the online publications, and slides of recent talks.

Some mathematical highlightsOne of my favourite results in mathematics is the following: \[ 1 + \frac{1}{4} + \frac{1}{9} + \cdots = \frac{\pi^2}{6}. \] Leonard Euler's wild and brave explanation is given here.
| Stacking up dominoes Apparently you can stack up dominoes in balance in the following way ![]() To see how click here (PDF). |
Roller which are not round! Look at the picture below. It shows two `rollers' in the shape of a 50p with a book on top. What will happen to the vertical distance between the book and the table as you roll the book along?

| Normal vibration modes of a circular membrane Imagine an elastic circular membrane fixed along its circular boundary but otherwise free to vibrate. There are a number of different normal vibration modes which are possible.

| The double pendulum A double pendulum consists of two rigid arms that are joined by a low friction bearing.
