I am a passionate advocate of mathematics education at all levels, from primary school to university. I believe that an appreciation of the beauty and power of mathematics enhances people’s lives, and fair access to high-quality mathematics education is crucial for both individual and national success.In 2010, I became Chief Executive of the mathematics education charity, MEI. Since March 2013, I have been Director of the National Centre for Excellence in the Teaching of Mathematics (NCETM), whilst continuing as MEI’s Chief Executive.As Chief Executive of MEI, I head up an organisation with nationally respected expertise in maths curriculum development and teacher professional development. MEI plays a key role in the development and leadership of major government-funded programmes to improve maths education: the Advanced Mathematics Support Programme (AMSP), the National Centre for Excellence in the Teaching of Mathematics (NCETM) and the Maths Hubs Programme.Before joining MEI in 2000, I taught maths in the state sector for 10 years, both in secondary schools and in a large Further Education College. I have extensive leadership experience in teacher professional development, curriculum development and assessment in maths. My curriculum development work includes working on the reforms that led to the current GCSE and AS/A level Mathematics and Further Mathematics qualifications, and pioneering the development of the Core Maths qualifications. This summer I chaired the Department for Education’s Expert Advisory Group on maths to 18.I was awarded an MBE for services to education in 2015.
