Julian Edgar started his working life freelancing for photography magazines. He then worked as a secondary school teacher for eight years, teaching humanities, before leaving teaching and becoming a full-time automotive writer. He edited a national Australian automotive print magazine before becoming editor of AutoSpeed, an online car magazine. Along the way he wrote extensively for Silicon Chip, an electronics hobbyist magazine, while contributing articles to publications in Australia, the UK and the US.He has been aerodynamically modifying his own cars for nearly 25 years. He was the first automotive journalist to extensively wool tuft cars and write about the results (starting in 1989),… and use Magnehelic gauges to directly measure aerodynamic pressures (in 2000) - both approaches now widely used by amateurs.Julian lives in a hamlet 80 kilometres north of Canberra, Australia. He spends much of the week playing in his home workshop - for the rest of the time, he trains government Public Servants in high level writing skills.
