Raman Sundrum is the John S. Toll Chair and Distinguished University Professor of Physics at the University of Maryland, College Park. He also is the Director of the Maryland Center for Fundamental Physics. Previously, he was the Alumni Centennial Chair in the Department of Physics and Astronomy at the Johns Hopkins University. He earned his BSc in Mathematics at the University of Sydney in Australia and his PhD in theoretical particle physics at Yale. He did postdoctoral research at Berkeley, Harvard, Boston University, and Stanford. He works on theoretical particle physics, primarily the structure of the fundamental forces and their connections to possible extensions of Relativistic Spacetime, such as Supersymmetry and Extra Dimensions. He also studies their possible roles in the very early Universe. His research provides theoretical templates for a broad range of experiments, from the CERN Large Hadron Collider to precision cosmological measurements. Raman is a Fellow of the American Physical Society as well as the American Association for the Advancement of Science, is a Distinguished Visiting Chair at the Perimeter Institute in Canada, and was formerly a Moore Fellow at CalTech. In 2019 he was awarded the J.J. Sakurai Prize for Theoretical Particle Physics of the American Physical Society along with his former collaborator, Lisa Randall of Harvard University, for their pioneering of what are now known as the “Randall-Sundrum” models of higher-dimensional spacetime. Abstract: Raman Sundrum will review the mechanism of “cosmological collider physics” in which future precision cosmological measurements may allow us to probe particle physics and cosmic inflation at energies which are orders of magnitude above those of terrestrial particle colliders such as the LHC. He will apply this mechanism to searching for remnants of the grand unification of (non-gravitational) fundamental forces and other plausible high energy "targets" and discuss recent work showing how gravitational wave cosmology may provide complementary insights on inflationary dynamics in the very early universe. The colloquium will be livestreamed on the ICTP YouTube channel Refreshments will be served at the end of the talk on the Leonardo Building Terrace
