Graham Lyons grew up in Adelaide. After graduating in agricultural science he spent two years travelling the world, which included a six-month African safari. His interest in fiction writing was stimulated by long lonely evenings in the Eastern Solomons during a three-year stint as an agricultural development officer in the early 1980s. Then followed fifteen years running the family farming interests in South Australia, while based at the 'Glen Bold' Angus cattle stud at Echunga in the Adelaide Hills.
His first published story appeared in Australian Playboy in 1988, and in 1991 he published But When I Landed, a short story collection with a blend of fact and fiction. He then turned to matters of ecology, health, economics and population and co-authored a series of books published by Praeger/McMillan/St Martin's Press in the 1990s.
With the sale of the farms in 1997 he studied public health, followed by a PhD in micronutrient nutrition and has since worked as a researcher at the University of Adelaide's Waite Institute, investigating the effects of selenium and iodine in plants and humans, and has written numerous scientific articles and presented findings at overseas conferences.
