Raman Sundrum is an influential physicist known for his contributions to theoretical physics, particularly in the fields of cosmology, string theory, and quantum gravity. He is best recognized for his work on models involving extra dimensions, including the idea that our 3-dimensional universe could be a brane embedded in a higher-dimensional space. One of his notable contributions is the "Randall-Sundrum" models, developed in collaboration with Lisa Randall.

Raman Sundrum and Lisa Randall proposed the Randall–Sundrum model to address the hierarchy problem. A warped spacetime metric produces an exponential relation between physical scales on two branes, even with only one compact additional spatial direction. In their 1999 construction, the Standard Model fields occupy one brane. The proposal makes the geometry of spacetime part of the explanation for a large separation of energy scales, with characteristic massive spin-two excitations as possible tests.[ref]
