Brian Greene is a theoretical physicist, author, and science communicator known for his work in string theory and cosmology. As a professor at Columbia University, he has made significant contributions to the understanding of the fundamental nature of the universe, particularly in areas related to extra dimensions, quantum mechanics, and the fabric of space-time. His books, including The Elegant Universe, The Fabric of the Cosmos, and Until the End of Time, have helped bridge the gap between complex physics concepts and mainstream audiences.

In addition to his academic research, Greene is a passionate advocate for scientific literacy and education. He has hosted PBS documentaries based on his books and co-founded the World Science Festival, an annual event that brings together leading thinkers to discuss breakthroughs in physics and beyond. His engaging storytelling and ability to simplify complex ideas have made him one of the most well-known figures in modern theoretical physics.
