Sean Couch is a theoretical astrophysicist specializing in the study of the core-collapse supernova mechanism using large-scale numerical simulation. His recent contributions include demonstrating the enormous impact multidimensional stellar progenitor structure has on the supernova mechanism and showing that turbulence is playing a crucial role in aiding successful explosions. Couch is also interested in massive stellar evolution, the origin of the elements, black hole accretion, gamma-ray bursts and radiative transfer. His simulations are run using hundreds of thousands of processing cores in parallel on the world’s fastest supercomputers.
Couch earned his Ph.D. in astrophysics from the University of Texas at Austin, where he worked with Professors J. Craig Wheeler and Milos Milosavljevic. He was a Hubble Fellow at the University of Chicago and, most recently, a senior postdoctoral fellow in Theoretical AstroPhysics Including Relativity (TAPIR) at Caltech in Pasedena, Calif.
