Professor in Astronomy & AstrophysicsScientist, Theoretical Astrophysics Group, Fermi National Accelerator Laboratory
A theoretical physicist, Gnedin (pronounced GUHNED in) pursues wide–ranging research interests that include general relativity, the physics of interstellar space and cosmology. He uses numerical cosmological simulations to create virtual universes for the study of galaxy formation, the formation of supermassive black holes, and the evolution of intergalactic gas and dust. He has performed simulations on powerful supercomputers since the mid–1990s at the National Center for Supercomputing Applications in Illinois. These simulations depict phenomena such as the web–like distribution of matter in the universe and an exploding star blasting gas out of a small galaxy. His honors include a 2002 National Science Foundation Career Award.
