Arianna Huffington is the co-founder and former editor-in-chief of the Huffington Post Media Group, a nationally syndicated columnist, and author. Originally from Greece, Huffington moved to England when she was 16 and graduated from Cambridge University with an M.A. in economics. At 21, she became president of the famed debating society, the Cambridge Union, and by 22 penned her book "The Female Woman." Today, Huffington is author of 13 books. Her 14th book, "Thrive: The Third Metric To Redefining Success And Creating A Life Of Well-Being, Wisdom and Wonder" will be published in March 2014. In 2005, she launched The Huffington Post, which quickly became one of the most widely-read, linked to, and frequently-cited media brands on the Internet. In 2012, the site won a Pulitzer Prize for national reporting. In August 2016, Huffington stepped down from her role at The Huffington Post to devote her time to a new health and wellness initiative, Thrive Global.
