Mike Norman has been a leader in computational astrophysics for over 45 years. Some of his influential work includes: - Cosmic jet simulations in the early 1980s which helped explain phenomena from galactic centers. - Pioneering the use of adaptive mesh refinement in the 1990s to achieve dynamic load balancing on supercomputers. - Massive cosmology simulations in the late 2000s with over 100 trillion particles using thousands of processors across multiple supercomputing sites, producing petabytes of data. - Developing end-to-end workflows in the 2000s to couple supercomputers, high-speed networks, and large visualization systems to enable real-time analysis of extremely large astrophysics simulations.
