Quaglia has held a variety of jobs, among them photographer, owner and barman of a pub, internet entrepreneur and politician. From the beginning of 1995 to the end of 1997, he was a Councilor in Genoa.^[1] Since 1989, he has been active in science fiction fandom. He has over a number of years occasionally written articles for the Science Fact & Science Fiction Concatenation,^[2] the SF zine that has won the most Eurocon Awards.^[3] Between 2002 and 2013 was vice-chairman of the European Science Fiction Society, the organization which coordinates the annual Eurocon science fiction convention.

In 1994 he became friends with American science fiction writer Robert Sheckley. In 1999 he and Sheckley traveled together around Europe for over a month, the first of a number of long journeys they took together. Some of Quaglia's articles, videos and photographs of these trips can be found on the Internet.^[4][5] In 2004, Quaglia and Sheckley began planning to write two books together, a project which became public a few months before Sheckley's death, in an article published by the Ukrainian press during Sheckley's last journey, a tour of the Ukraine together with Quaglia.^[6] Sheckley's death put an end to this project.

In 2003, Quaglia and British writer Ian Watson met and became friends, which led to a literary collaboration. Together they wrote the collection of My Beloved stories, some of which are available on the Internet, having been published by Helix SF,^[7] Flurb^[8] and in the United States, Clarkesworld Magazine.^[9] Other stories have been published in the American magazine Weird Tales, the Canadian anthology Lust For Life,^[10] New Writings in the Fantastic,^[11] several Mammoth Books of Best New Erotica: Volume 7,^[12] Volume 9^[13] and Best of Best New Erotica,^[14] and in other books. In 2009 these stories were collected into an anthology, The Beloved of My Beloved, published by NewCon Press, and launched in March–April 2009 at the Eurocon in Fiuggi and the Eastercon in Bradford.
