Harari originally specialized in world history, medieval history and military history. His current research focuses on macro-historical questions such as: What is the relationship between history and biology? What is the essential difference between Homo sapiens and other animals? Is there justice in history? Does history have a direction? Did people become happier as history unfolded? What ethical questions do science and technology raise in the 21st century?

Harari is the author of Sapiens: A Brief History of Humankind, Homo Deus: A Brief History of Tomorrow, 21 Lessons for the 21st Century, Sapiens: A Graphic History, and more recently, the children's book series "Unstoppable Us".

Born in Israel in 1976, Harari received his PhD from the University of Oxford in 2002. In 2019, following the international success of his books, Yuval Noah Harari and Itzik Yahav co-founded Sapienship: a social impact company with projects in the fields of entertainment and education. Sapienship’s main goal is to focus the public conversation on the most important global challenges facing the world today.
