Chris Johnson

Chris Johnson is a Distinguished Professor of Computer Science and founding director of the Scientific Computing and Imaging (SCI) Institute at the University of Utah. He also holds faculty appointments in the Departments of Physics and Bioengineering. His research interests are in the areas of scientific computing and scientific visualization. In 1992, Dr. Johnson founded the SCI research group, now the SCI Institute, which has grown to employ over 200 faculty, staff and students. Professor Johnson is a Fellow of AIMBE (2004), AAAS (2005), SIAM (2009), and IEEE (2014). He has received a number of awards, including a NSF Presidential Faculty Fellow award from President Clinton, the Governor’s Medal for Science, the IEEE Visualization Career Award, the IEEE IPDPS Charles Babbage Award, the IEEE Sidney Fernbach Award, and the Rosenblatt Prize.

Valerio Pascucci

Valerio Pascucci is the John R. Park Inaugural Endowed Chair of Computer Science and founding Director of the Center for Extreme Data Management Analysis and Visualization (CEDMAV) of the University of Utah. Valerio is also a Faculty of the Scientific Computing and Imaging Institute, of the School of Computing, University of Utah, and a Laboratory Fellow, of PNNL. Before joining the University of Utah, Valerio was the Data Analysis Group Leader of the Center for Applied Scientific Computing at Lawrence Livermore National Laboratory, and Adjunct Professor of Computer Science at the University of California Davis. Valerio's research interests include Big Data management and analytics, progressive multi-resolution techniques in scientific visualization, discrete topology, geometric compression, computer graphics, computational geometry, geometric programming, and solid modeling. Valerio is the coauthor of more than one hundred refereed journal and conference papers and has been an Associate Editor of the IEEE Transactions on Visualization and Computer Graphics.


Demonstrate end-to-end high-performance computing (HPC) and Big Data analytics capabilities on Intel® software and hardware resources integrated with current and future plaforms.
