He published his first work in 1983.{{cite web|url=https://www.gregegan.net/BIBLIOGRAPHY/Bibliography.html |title=Bibliography |publisher=Gregegan.net |date=7 August 2014 |access-date=23 August 2014}} He specialises in hard science fiction stories with mathematical and quantum ontology themes, including the nature of consciousness. Other themes include genetics, simulated reality, posthumanism, mind uploading, sexuality, artificial intelligence, and the superiority of rational naturalism to religion. He often deals with complex technical material, like new physics and epistemology. He is a Hugo Award winner (with eight other works shortlisted for the Hugos) and has also won the John W. Campbell Memorial Award for Best Science Fiction Novel.{{sfadb|Greg_Egan}} His early stories feature strong elements of supernatural horror.

Egan's short stories have been published in a variety of genre magazines, including regular appearances in Interzone and Asimov's Science Fiction.

In 2002, Egan co-authored two papers about Riemannian 10j symbols, spin networks appearing in Riemannian quantum gravity, together with John Baez and Dan Christensen. Spin networks also play a central role in his novel Schild's Ladder released the same year.

In 2014, Egan conjectured a generalization of the Grace–Danielsson inequality about the relation of the radii of two spheres and the distance of their respective centres to fit a simplex between them to also hold in higher dimensions, which later became known as the Egan conjecture. A proof of the inequality being sufficient was published by him in 2014 under a blog post of John Baez. They were lost due to a rearrangement of the website, but the central parts were copied into the original blog post. Further comments by Greg Egan on 16 April 2018 concern the search for a generalized conjecture involving ellipsoids.{{cite web|access-date=2023-11-22|author=John Baez|date=2014-07-01|language=en|title=Grace–Danielsson Inequality|url=https://blogs.ams.org/visualinsight/2014/06/01/grace-danielsson-inequality/}} A proof of the inequality also being necessary was published by Sergei Drozdov on 16 October 2023 on ArXiv.{{cite arXiv|author=Sergei Drozdov|language=en|title=Egan conjecture holds|date=2023 |class=math.MG |eprint=2310.10816 }}

In 2018, Egan described a construction of superpermutations, thus giving an upper bound to their minimum length. On 27 February 2019, using ideas developed by Robin Houston and others, Egan produced a superpermutation of seven symbols of length 5906, breaking previous records.{{cite web |last1=Egan |first1=Greg |title=Superpermutations |url=https://www.gregegan.net/SCIENCE/Superpermutations/Superpermutations.html |access-date=2 February 2019}}{{cite web |last1=Klarreich |first1=Erica |title=Mystery Math Whiz and Novelist Advance Permutation Problem |url=https://www.quantamagazine.org/sci-fi-writer-greg-egan-and-anonymous-math-whiz-advance-permutation-problem-20181105/ |website=Quanta Magazine |date=5 November 2018 |access-date=13 May 2019}}
