My research interests include (i) automatic assessment of mathematics using computer algebra, in particular the development of the STACK system, (ii) mathematical problem solving using Moore method and similar student-centred approaches and (iii) curriculum development. I'm the author of a number of books, including "How Round is Your Circle", which illustrates and investigates many links between mathematics and engineering using physical models.
I am joint editor of Teaching Mathematics and its Applications, a journal of the Institute for Mathematics and its Applications.
I attended Bishop Wordsworth's School, Salisbury and left in 1992 to read mathematics at Brasenose College, Oxford. I then completed an MSc in Nonlinear Mathematics and a PhD in Mathematics at the University of Bath.
From 2013-2015 I was Senior Lecturer in Mathematics Education in the Mathematics Education Centre at Loughborough University. From 2000-2013 I was employed by the School of Mathematics at the University of Birmingham. From 2000-2011 I was seconded half time to the UK Higher Education Academy "Maths Stats and OR Network" to promote learning and teaching of university mathematics.
