## Research

I am Professor of Mathematics Education as part of the Centre for Technology Enhanced Science Education. My research interests include (i) automatic assessment of mathematics using computer algebra, and (ii) problem solving using Moore method and similar student-centred approaches. A practical outcome of this is the STACK computer aided assessment system.

For more information, see the demonstration site and my book on this subject: http://www.stack.ed.ac.uk/.

## Some mathematical highlights

 Euler's sum One 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. The game of Hex Hex is a connection strategy game for two players. It is simple to learn, great fun to play and has some deep mathematics behind it. Some hex resources.
