I am a former secondary school mathematics teacher who now works as a Principal Research Associate at the UCL Knowledge Lab, UCL Institute of Education and is currently a Co Principal Investigator (with Celia Hoyles) for the Nuffield Foundation Cornerstone Maths project, which extends the earlier project funded by Li Ka Shing Foundation. (www.cornerstonemaths.co.uk).

Prior to taking up my role at LKL, I worked at the University of Chichester where I designed and led master's level postgraduate courses and projects for practising secondary mathematics teachers, often with an emphasis on the development of innovative pedagogies involving the use of mathematical technologies. 

I directed the UK evaluation of Texas Instruments’ TI-Nspire handheld technology and the European evaluation of their TI-Nspire TI-Navigator network classroom system. From 2009-2012 I had the role of the project lead partner in the EU Comenius funded project ‘EdUmatics’, which involved 20 Partners from seven EU countries (www.edumatics.eu).

I have edited and authored 3 books, the most recent of which is The Mathematics Teacher in the Digital Age (with Ornella Robutti and Nathalie Sinclair, published 2014). 

I am an active member of The Mathematical Association, Association of Teachers of Mathematics and a Fellow of the Institute of Mathematics and its Applications. I currently serve as a co-opted member of the Executive Committee for the British Society for the Learning of Mathematics and I co-convene (with Dr Alf Coles) the Mathematics Education SIG for the British Educational Research Association.
