Brandon Winn Sanderson is a renowned American author of high fantasy, science fiction, and young adult books. He is best known for the Cosmere fictional universe, where most of his fantasy novels, including the Mistborn series and The Stormlight Archive, are set. Apart from the Cosmere, Sanderson has written several young adult and juvenile series, such as The Reckoners, the Skyward series, and the Alcatraz series.

He gained notable recognition for completing Robert Jordan's epic fantasy series, The Wheel of Time. Sanderson has also crafted two graphic novels, including White Sand and Dark One. He is credited with formulating Sanderson's Laws of Magic and popularizing the concept of "hard magic" and "soft magic" systems.

In 2008, Sanderson began a podcast called Writing Excuses, with author Dan Wells and cartoonist Howard Tayler, discussing topics related to genre writing and webcomics. In 2016, the American media company DMG Entertainment acquired the movie rights to Sanderson's entire Cosmere universe, although the rights were later returned to Sanderson.

Sanderson's March 2022 Kickstarter campaign became the highest-grossing in history, garnering 185,341 backers who pledged $41,754,153.
