Robert Rosner served as Argonne National Laboratory's Associate Director for physical, biological and computing sciences and as its Chief Scientist from 2002 until 2005, and as laboratory director from 2005 until 2009. A fellow of the American Academy of Arts and Sciences, his scientific specialty is plasma astrophysics–the physics of the sun and the stars. He led the collaboration of Argonne and University of Chicago scientists who created the Center for Astrophysical Thermonuclear Flashes and directed the center from its founding in 1997 until 2002. The center develops simulations of exploding stars with computer codes that can be adapted for application to other fields.
