Bio: Paul Sutter received his Ph.D. in Physics from the University of Illinois at Urbana-Champaign as a Department of Energy Computational Science Graduate Fellow. He then spent three years as a Postdoctoral Fellow in Next-Generation Cosmic Probes at the Paris Institute of Astrophysics, and is currently an INFN Fellow in Theoretical Physics in Trieste, Italy, and a Visiting Scholar at the Ohio State University’s Center for Cosmology and Astro-Particle Physics. He is inexplicably drawn to positions with very long titles.
