Helen Pilcher, author of Life changing, is a tea-drinking, biscuit-nibbling science and comedy writer. She has a PhD in Cell Biology from London's Institute of Psychiatry. A former reporter for Nature, she now specializes in biology, medicine and quirky off-the-wall science, and writes for outlets including New Scientist and BBC Focus. Unusually for a self-proclaimed geek, Helen also used to be a stand-up comedian before the arrival of children meant she couldn't physically stay awake past 9pm. She now gigs from time to time, and lives in rural Warwickshire with her husband, three kids and besotted dog.
