Walker, Ian: - "Ian Walker splits his time across two related worlds. By day, he is an environmental psychologist at the University of Bath, specialising in transport choices, traffic safety, energy consumption and water use. As you will see from his textbooks, he also teaches research methods and statistics at a whole range of levels from entry-level introductions up to doctoral level. Ian's professional interest in clean transport and traffic safety also extends into his personal life, where he takes part in ultradistance bicycle racing - an activity explored in his new book Endless Perfect Circles. This introduces readers to the extraordinary world of nonstop bicycle races that last for weeks at a time. It goes on to describe how Ian won a tough 4300-kilometre cycle race before breaking the Guinness World Record for the fastest ever bicycle crossing of Europe."
