Indian-born physicist E. C. George Sudarshan helped lay key theoretical foundations of modern physics while working at American universities including Rochester, Syracuse, and the University of Texas at Austin. He co-developed the V-A theory of weak interactions, later incorporated into the electroweak theory, and introduced the Glauber-Sudarshan representation, which gave quantum optics its mathematical basis for describing light beyond classical limits. His work underpins technologies from particle physics to quantum computing, though he never received the Nobel recognition many believed his contributions warranted.
