Butler University President Jim Danko announced last Thursday  the keynote speaker at the 2013 commencement will be New York Times bestselling author John Green.

His most recent work, “The Fault in Our Stars,” is what earned him the honor from the Times. He also is known for his 2012 novel, “Looking for Alaska.”

Green also has  a YouTube channel entitled “Vlogbrothers,” where he and his brother post videos for his viewers, or “nerd fighters,” as he calls them.

Green was born in Indianapolis but moved within three weeks. He has since returned and lives in Indianapolis with his wife, son, dog and another child on the way.

In the announcement, Danko said he was “extremely pleased” to have Green as the keynote speaker. He also said Green will be awarded an honorary doctorate of letters.

Green said he has stopped all his other work to focus on delivering a good speech.

“To be honest, I’m very nervous and anxious,” Green said. “It’s a big honor and responsibility.”

Green said while living in Indianapolis, his experiences with Butler have included taking night classes and attending basketball games. The character in his latest book attends a game.

He said he has attended a few commencement speeches in his life, and very few have actually made an impact.

“I hope to not make the graduates sit through a dry speech like I have in the past,” Green said. “Hopefully, Hinkle has air conditioning because that should make me more bearable to listen to.”

Green said he is just as excited as he is nervous for the speech. He said his Twitter account, which boasts more than 1.4 million followers, has received many messages from excited fans.

“My message will be one that is hopeful and honest,” Green said, “but, most importantly, not too long and hopefully a little funny.”
