Nima Arkani-Hamed is one of the leading theoretical physicist of his generation with broad interests in high-energy physics, string theory and cosmology. He has taken a lead in proposing new physical theories that can be tested at the Large Hadron Collider at CERN. His research has shown how the extreme weakness of gravity might be explained by the existence of extra dimensions of space, and his recent work focuses on a reformulation of the foundations of quantum field theory. He is a professor at the prestigious Institute for Advanced Study in Princeton, and the inaugural director of the Center for Future High Energy Physics in China. He has received numerous awards, including the Fundamental Physics Prize in 2012.
