Ali isn't a Scientist. She doesn't actually know much about science at all, but managed to conceal this fact when hooking up a volunteer position with the Naked Scientists.
Ali did an engineering degree in Australia before realising that what she liked more than engineering stuff was talking about engineering stuff. Hence, she spent a couple of months in Winter 06/07 helping out and learning the ropes. Back in her baked brown homeland, Ali worked in the wind energy industry.
