Gregory Crocetti is a microbial ecologist, science educator, writer and advocate for microbes.

His PhD research at the University of QLD and subsequent post-doctoral research at UNSW investigated microbial population dynamics across a range of environments, including mouse intestines, sponges, seaweed and sewage. He now co-directs the art-science collective Scale Free Network, who create picture books, graphic novels, workshops, exhibitions & installations, which draw on the microscopic world.

Scale Free Network (SFN) is an art-science collaborative and micro-publisher founded in 2007 by conceptual artist Briony Barr and microbial ecologist, Dr Gregory Crocetti. Based in Melbourne, SFN creates interdisciplinary workshops, installations, artworks, picture books and graphic novels inspired by the microscopic world (99 % of biodiversity on Earth is invisible to the naked eye, so there’s a lot to work with). SFN projects aim to ‘visualise the invisible’ at the same time as questioning the human-scale lens through which we relate to the world.

Gregory is one of the members of Carbon Arts’ Australian Future Foods Lab project, collaborating with us on the Native Botanicals dinner (2013), Elixir Bar (2013) and Of this Earth (2019).
