For his day job, Luke Freeman works in Digital Marketing at the ABC (Australian Broadcasting Corporation). This is the part where he must state that his views are his own and not that of his employer. Unlike most of the other writers here, he does not have a professional or academic background in science, just a lifelong love of it - largely thanks to Wallace & Gromit's Techno Quest and the works of Douglas Adams.
Luke's background is in communications and marketing which is why he is well versed in the dark arts of deception... well, at least knowing how easily people are manipulated. He spent his childhood home-schooled on a hobby farm, heavily involved with the local church and competing internationally as a rower.
His skepticism started by the critical thinking required for the self-directed learning that was encouraged by his parents when home-schooling. An upbringing as an evangelical Christian was a foundation of his skepticism towards the faiths of others, which eventually led him to direct that same scrutiny to his own beliefs. The nail in the coffin was in part due to the abundance of pseudoscience being peddled to elite athletes to "get that extra 1%".
In 2011, Luke discovered that there was a word for his lifestyle and a community surrounding it by stumbling upon The Skeptics Guide to the Universe on iTunes. This revelation let to a slight addiction to skeptical podcasts (including The Pseudo Scientists), blogs, tweeps, books and skeptics in the pub.
When he's not at work you'll probably find him playing pub music, brewing beer, cycling around the streets, getting out into nature, listening to podcasts, stuck into some book about science and trying to squeeze in some healthy skepticism (and hopefully activism on that front).
You can find "παν μέτρον άριστον" tattooed to his back, meaning that there truly is a good reason to ask him to take his shirt off.
His favourite quote is: "Human beings, who are almost unique in having the ability to learn from the experience of others, are also remarkable for their apparent disinclination to do so" by the late, great Douglas Adams.
