Raman Sundrum is the John S. Toll Professor of Physics at the University of Maryland. He did his undergraduate studies atUniversity of Sydney in Australia and received his Ph.D. fromYale University. He did his postdoctoral research at UC Berkeley, Harvard, BU and Stanford. He joined the faculty of the Department of Physics and Astronomy of the Johns Hopkins University in 2000, and became one of two Alumni Centennial Chairs there. In 2010, he moved to the University of Maryland. His research in particle physics and cosmology focuses on theoretical mechanisms and observable implications of extraspacetime dimensions,supersymmetry, and strongly coupled dynamics. His highest impact contribution to the field is a class of extra-dimensional models called theRandall–Sundrum models, first published in 1999 withLisa Randall. Sundrum is a UMDDistinguished University Professor.
