David is an assistant principal, a geography teacher in the Lincolnshire region, and a writer and illustrator of education ideas. He is also a specialist leader of education (SLE) and evidence lead education (ELE). His debut book, co-authored with Oliver Caviglioli, was 'Organise Ideas, Thinking by Hand and Extending the Mind'.

Emma grew up in Leicestershire and attended Liverpool John Moores University where she studied Science Education. She has taught in schools across the county and has been a Local Authority Lead teacher. In 2002, she became a consultant for the National Numeracy Strategy, supporting numerous schools.

In 2004 she joined The Latimer Primary school where she spent the next 13 years, initially as a classroom teacher, moving on to become assistant head, then deputy head and finally forming one of the UK's first all-female co-headships which ran for eight years, and where Emma wrote and delivered training for staff at all levels across the county, as well as complete induction programmes for NQTs through her work with Affinity Teaching School Alliance.

After 20 years in primary teaching, Emma left to join Discovery Schools Academy Trust where she is currently their Research and CPD lead, devising and writing training for staff at all career stages, but specialising in CPD for early career teachers. She is the founder of 'NewEd - Joyful CPD for early career teachers', a not-for-profit approach to CPD to encourage positivity amongst the profession and help to retain teachers in post. She is a columnist at the TES, an ambassador for the The Gender Equality Collective, and a member of the WomenEd community, regularly presenting at events and writing contributions.

Emma is an advocate of balance in leadership and family life and she regularly speaks at events across the country on how part-time leadership and flexible working can be a hugely successful model in organisations. She is also the self titled 'Chaos Coordinator' of her home in Leicestershire where she lives with her infinitely patient husband Tom and their three young children.

Oliver Caviglioli is uniquely placed to bridge the gap between education and graphic design. A former special school head teacher, Oliver learned design principles from an early age from his architect and typographer father. Four decades of reading educational research found its visual expression in his spectacular, image-rich book 'Dual Coding With Teachers'.
