Duncan gained a PhD in science in 1999 and then went on to work as a scientist before becoming a teacher in various disciplines and finally becoming a writer.
His maths book originates in his tutoring of the subject. His dance book originates from his hobby of many years. His ecotourism books originate from his extreme obsession with exploration and nature that has led to months of most years being dedicated to exploring with a tent and sleeping bag the corners of the planet on which he has found himself. Finally, his fiction books are a later arrival and are inspired by his varied life exploring the world, science, language and the incredible breadth of human knowledge. His fiction books touch on many things including the nature of being human, the nature of human civilisation and what might become of this species and its creations in the future.
