Peter MacInnis is a science writer who lives in Sydney. He began writing science talks for radio in 1985 and has been at it ever since, but his main job for more than thirty years was as an educator, either as a teacher, or as a bureaucrat, or in one of two museums that he worked in, and most recently, writing science content for an online encyclopaedia. Peter has now officially "retired from teaching" and works full-time as a writer, in between travelling as much as he can.
