I am a former secondary school mathematics teacher who now works as a Principal Research Lead for the ERDF-funded EDUCATE Project at the UCL Knowledge Lab, UCL Institute of Education. I lead the research strategy for the project and co-ordinate the research training element of the programme that will reach 250 industry founders of educational technology products and services. In 2017, I completed (as Co Principal Investigator with Celia Hoyles) a three-year project funded by the Nuffield Foundation on “Digital pedagogies for mathematics teaching”, which extends the earlier Cornerstone Maths project (2012-14) funded by Li Ka Shing Foundation. My role prior to joining UCL Knowledge Lab was Programme Lead of a large Master’s level course in mathematics education, which involved online and off-site delivery in collaboration with five different Local Authority Education Departments. In addition, I led a number of government and industry-funded teacher and curriculum development projects involving the use of innovative 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 was the project lead partner in the EU Comenius funded project ‘EdUmatics’, which involved 20 Partners from seven EU countries. 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 by Springer Nature in 2014). This continues to be the most successful book in its series (Mathematics Education in the Digital Era) with over 23,000 downloads as of November 2018. A second edition is in development. I am an active member and former Trustee of both The Mathematical Association and the Association of Teachers of Mathematics. I am a Fellow of the Institute of Mathematics and its Applications and a Member of the London Mathematical Society.
