Short Bio and Current Research Interests:

Dr. Ronald D. Kriz is an Associate Professor in the College of Engineering at Virginia Tech. He recieved the Ph.D. and M.S. degrees from Virginia Tech in 1976 and 1979 (Engineering Science and Mechanics) and B.S. degree from California Polytechnic State Univeristy in 1973 (Aeronautical Engineering). He has published over 50 technical papers in referred journals and conference proceedings in the area of mechanics and material science and engineering. Prior to coming to Viriginia Tech in 1990 he was active in Materials Research Engineering research at NIST for ten years. During that time, he used supercomputers to simulate the physics of stress wave propagation in anisotropic media. Several patents resulted from these studies that used visual data analysis tools to make these discoveries. Subsequently Dr. Kriz returned to Virginia Tech and continued the development of visual data analysis tools as they related to supercomputer simulations. He was the founder of the Laboratory for Scientific Visual Analysis (LSVA) in 1991 as an academic affiliate with NCSA. For the last 17 years he has worked with faculty in developing and using visual data analysis tools in the interpretation of their simulation results. In 1996 he was awarded NSF ARI funds to build a CAVE(tm) facility ("VT-CAVE(tm)") in collaboration with NCSA as part of Virginia Tech's Advanced Communications and Information Technology Center (ACITC) which is now Torgersen Hall. He is the Director of the Virginia Tech University Visualization and Animation Group ( UVAG) in the ACITC (1996) He is also PI of the Virginia Tech Scientific Modeling and Visualization Classroom (SMVC), also an ACITC activity, which was an educational grant co-sponsored by Sun Microsystems Inc and Visual Numerics Inc. He was also the PI on the NSF Combined Research and Curriculum Development ( CRCD) NSF grant that used the SMVC and developed extensive Web Java-based educational modules. Here are two concept papers: 1) "Dr. Kriz's thoughts on scientific research, high performance computing (HPC), scientific Visualization (SV), and the network", and "Concept Paper on Future Use of Visualization and Virtual Environments in Research, Education, and Outreach at Virginia Tech".
