Dr Kirby, Teacher of Chemistry 

Neil KirbyDr Kirby was born in London, spending his formative years in Surrey and the home counties, with a couple of years in Australia - where he learnt to swim, play cricket and make a real BBQ.

On completion of his doctorate in Chemistry, at the University of Sussex, Dr Kirby worked for Unilever as a Research Chemist, before moving to and IBM as a Materials Specialist. After several years in the electronics industry, working in China, USA and Europe, he retrained as a chemistry teacher and taught in schools in the UK and China, with senior roles as Head of Department and High School Principal.

Mrs Ryzak-McGhee believes that Economics is the perfect subject for anyone who wants to learn how to think, not what to think. She is (very) excited to help a classroom of keen and mathematically able economists to collaboratively explore some of the big questions about the society they live in, such as whether we can accurately model human behaviour and how governments can best respond to economic and social problems like inflation and the cost of living crisis.

In her spare time she enjoys reading, baking and going for long walks.

Most often found: exploring the great outdoors with her daughters.


Mr Tizard, Lead Teacher of Outreach and Teacher of Mathematics

Phil tizard

Mr Tizard grew up in Surrey, before leaving to study Maths at Nottingham University.  His three years in Nottingham emboldened him to travel in the years that followed. From Ghana to Syria, Israel to Honduras and many places in between, they each had their own unique charm. However, in terms of eye-opening experiences, a Friday night in Nottingham is probably still the most formative.

Teaching since 2011, Mr Tizard has spent the last 8 years working at local Sixth Form Colleges in Godalming and Esher. He has developed a real love of working with students of this age, finding their enthusiasm and humour refreshing. He has held a range of different roles of responsibility throughout his career and has a real interest in pedagogy and getting the most out of his students.  

As part of his Outreach role, Mr Tizard is keen to get out and about and meet students in the local area. He is also very much looking forward to working alongside a range of other teachers, learning from them and offering support in any way he can.

In his spare time he can be found feeding his three kids, entertaining his kids, cleaning up after his kids and acting as mediator for his kids.

Most often found: recovering in a quiet place (see above).
