Gregory Crocetti


Gregory Crocetti is a microbial ecologist, science educator, writer and advocate for the roles and rights of microbes. Over a decade Gregory’s scientific research (at the Universities of QLD, NSW & Lund), explored the roles of different populations of bacteria in a range of environments – including those found in mouse intestines, sponges, seaweed, stromatolites and sewage.
Gregory then shifted his focus to science education, working for several years with CSIRO Education and then with Friends of the Earth Australia’s Emerging Technologies Project. In 2007, Gregory began a long-term collaboration with artist Briony Barr in the art-science collective, Scale Free Network ( In this role, Gregory has co-designed and delivered a vast range of art-science projects for diverse audiences, drawing inspiration from the microscopic world.
Gregory and Briony now co-create and publish a range of award-winning picture books and graphic novels – stories about microbes and their symbiotic partnerships with larger life forms. Together with CSIRO Publishing, Gregory and Briony co-publish the Small Friends Books picture book series for 8-12 year old children ( Their first graphic novel, The Invisible War ( won several publishing awards, including a ‘Notable of 2017’ from the Children’s Book Council of Australia and the ‘Most Outstanding Resource of the Year’ in the 2017 Australian Educational Publishing Awards.
