Formerly an IT specialist (with a PhD in data modelling), Graeme Simsion made his publishing debut with the wildly successful The Rosie Project, based on his own script for a short film of the same title. He has subsequently published two sequels, the standalone novel The Best of Adam Sharp, and a novel co-written with his wife, Anne Buist, Two Steps Forward.
In 2019, he released Don Tillman's Standardised Meal System, a book of recipes and tips in the voice of the protagonist of the Rosie series.
