Jude Ellison S. Doyle is an author, journalist, and comic book writer living in upstate New York.

Under his former pen name “Sady Doyle,” Jude founded the feminist blog Tiger Beatdown in 2008. He is the author of "Trainwreck: The Women We Love to Hate, Mock, and Fear... and Why" (Melville House 2016), which has been called "smart, funny and fearless" (Boston Globe), "compelling" and "persuasive" (New York Times Book Review). The Atlantic predicted that "Trainwreck will very likely join the feminist canon." Doyle’s second book, "Dead Blondes and Bad Mothers: Monstrosity, Patriarchy and the Fear of Female Power" (Melville House, 2019) was named a Best Non-Fiction Book of 2019 by Kirkus Reviews and was shortlisted for Starburst Magazine’s Brave New Words award. His first non-fiction book under his real name, "DILF: Did I Leave Feminism," will be published by Melville House in the fall of 2025.

In 2021, Jude published "Maw," a limited-series horror comic with artist A.L. Kaplan, for Boom! Studios. His follow-up, "The Neighbors" with artist Letizia Cadonici, was published in 2023, and was nominated for a 2024 GLAAD award for “Outstanding Comic.” Both are now available in collected edition, and Jude’s third series, "Be Not Afraid" with artist Lisandro Estherren, is forthcoming from Boom! Studios.
