Scientific Computing and Imaging Institute The Scientific Computing and Imaging Institute (SCI Institute) at the University of Utah integrates three major facets of scientific computing--visualization, simulation, and geometric modeling--into computational problem solving environments. SCI Institute researchers and technologists have contributed to solving computational problems in fields including combustion, fluid dynamics, petrochemical reservoir simulation, cardiology, neurosurgery, radiology, nuclear fusion, and the atmospheric diffusion of pollutants. One of the key missions of the SCI Institute is to provide integrated solutions and problem solving environments to help scientists in different disciplines solve their own computational problems. Dr. Christopher Johnson, Director of the SCI Institute According to SCI Institute Director Christopher Johnson, Internet2 high-performance networks provide a direct data channel to our collaborators throughout the country. From researching Grid applications to leveraging the interactive videoconferencing capabilities of the Access Grid, Internet2 provides the networking we need to pursue collaborative Grid-based research. SCI Institute researchers are using networking protocols such as multicast and IPv6 to accomplish their research while incorporating new and innovative networking solutions in a wide range of engineering and scientific application areas. The SCI Institute also houses two national research centers: the NIH NCRR Center for Bioelectrical Field Modeling, Simulation and Visualization and the DOE Advanced Visualization Technology Center (AVTC). Additionally, the SCI Institute houses the NIH-BISTI Program of Excellence in Computational Bioimaging and Visualization: Tools For Image Processing and Fusion, Interactive Visualization, and Inverse Problems.
