Emilio Baglietto is Associate Professor of Nuclear Science and Engineering at the Massachusetts Institute of Technology (MIT) and PhD Graduate of the Tokyo Institute of Technology. His research goals include improving the effectiveness and expanding the reach of 3-D, first-principles computational tools for nuclear reactor design. He notes that this work is applicable at the micro scale, to better understand physical interactions; at the component scale, to optimize designs; and at the full-system level, to validate new designs while taking into account complex system interactions. As a result, the technology promises to be a starting point for entirely new generations of innovation in a wide range of areas. He covers the role of Thermal Hydraulic Focus Area Lead for the Consortium for Advanced Simulation of Light-Water Reactors (CASL), the largest US Department of Energy program in the Nuclear Energy field.
