Jean-Louis Trudel was born in Toronto, Canada, and now lives in Quebec City. The holder of degrees in physics, astronomy, and the history and philosophy of science, he has devoted his writing career to science fiction (aside from occasional forays into fantasy).

Whether writing alone or in collaboration with Yves Meynard (using the symbionym Laurent McAllister), he has authored a trio of novels published in France, including the award-winning Suprématie (Bragelonne, 2009); four fiction collections; 26 young adult books published in Canada; and an introductory guide to the history of science fiction in French-speaking Canada, Petit Guide de la science-fiction au Québec (Alire, 2017). His short stories in French, numbering over a hundred, have appeared in magazines like Solaris and Galaxies, as well as various other venues. His short fiction in English (either original or in translation) has been published in several Canadian and American anthologies, but also in magazines including Asimov’s Science Fiction and On Spec, earning an honorable mention in The Year's Best Science Fiction: Thirty-Second Annual Collection (ed. Dozois; St. Martin's Griffin, 2015). His stories have been translated into several languages, most recently in the Italian anthology Solarpunk: dalla disperazione alla strategia (Future Fiction, 2021).

Alone or with Yves Meynard, he has been an Aurora Award finalist multiple times, winning for fiction in 1997, 2001, 2002, 2003, 2008, 2009, and 2010, and for non-fiction in 2007. Similarly, he has been a regular Prix Boréal finalist, winning for fiction in 1999, 2002, 2008, 2009, and 2010. In 2016, he won the short fiction category of the twinned Prix Boréal-Aurora Award and the non-fiction category in 2018. In 2001, he was awarded the Grand Prix de la Science-Fiction et du Fantastique québécois.

When time allows, he also translates (from English to French and French to English). Finally, he is part of the editorial team of ReS Futurae, the only French-language academic journal devoted to science fiction criticism.
