Previous career history:
After completing my undergraduate degree (Mathematics) and PGCE at the University of Cambridge, I began my teaching career at Aylesbury Grammar School.  I was appointed to Second in Maths at Dr Challoner’s High School in 2008 and as Head of Mathematics in 2012.  I have also held the position of Head of Year 8 and HoY 12.
What you hope to achieve as an SLE:
The importance of strong Mathematics teaching is paramount in inspiring pupils to enjoy the pursuit of this subject at every level and to feel confidence in their understanding of, and ability to use Mathematics.  As teachers, I firmly believe that we all have the capacity to continually learn and to further enhance our own practice.  I am keen to share excellent practice, including the use of IT in teaching and learning, providing students with access to outstanding teaching, through a collaborative approach.  Having seen a considerable increase in the number of students taking Mathematics at A-Level within DCHS, I am also keen to promote opportunities for students to study both Mathematics and Further Mathematics across other schools.
Specific areas of expertise, and how you might be able to help other schools:
The Mathematics Curriculum KS3-5
Stretching gifted and talented students in Mathematics
Data Analysis for tracking pupil progression and to inform planning
Teaching of AS and A2 Further Mathematics
Preparation for Oxbridge entrance in Mathematics
Use of IT in teaching and learning e.g. e-learning, Use of the IWB, graphical calculators, use of iPads 
Future career goals:
I am looking forward to the opportunity of working alongside fellow Mathematics teachers to promote outstanding teaching and learning, in addition to developing the skills of other middle leaders with this shared aspiration and also continually enhancing my own practice.
