Greg Egan 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 transfer, sexuality, artificial intelligence, and the superiority of rational naturalism over religion. He is a Hugo Award winner (and has been shortlisted for the Hugos three other times), and has also won the John W Campbell Memorial Award for Best Novel. Some of his earlier short stories feature strong elements of supernatural horror, while due to his more popular science fiction he is known within the genre for his tendency to deal with complex and highly technical material (including inventive new physics and epistemology) in an unapologetically thorough manner. Egan is a famously reclusive author when it comes to public appearances, he doesn't attend science fiction conventions, doesn't sign books and there are no photos available of him on the web.

Sus obras más conocidas pertenecen a la space opera, aunque, en los últimos años, se ha centrado en la fantasía sobrenatural de ambientación histórica y la fantasía épica de corte asiático, sin abandonar en ningún momento sus grandes obsesiones: la especulación lingüística y la creación de sociedades.

También ha sido jurado en diversos certámenes literarios, seleccionadora de varias antologías y ha promovido proyectos, centrados en la visibilidad de autoras españolas, como el canal de YouTube #LaCueva o el grupo de Goodreads #LeoAutorasFantásticas.
