Email: npolys@vt.edu

Dr. Nicholas F. Polys is Director of Visual Computing with Virginia Tech Research Computing Group and Affiliate Research Professor in the Department of Computer Science. He has developed interactive 3D graphic content and systems since 1998. His research interests lie at the center of graphics and Human Computer Interaction: the intersection of visualization, virtual environments, and perception. After his undergraduate research in Cognitive Science at Vassar College (1996), he jumped into the networked information space of the WWW developing audio, visual, and 3D assets and software. His doctoral work at Virginia Tech (2006) examined perceptual cues and layout behaviors for Information-Rich Virtual Environments for desktop to immersive platforms.

He is an ICAT fellow and member of ICAM, a member of ACM, IEEE Computer Society, and the Web3D Consortium. He is a co-author of the international standard (ISO) Extensible 3D (X3D), elected Director and President of the Web3D Consortium, and Chair of the Web3D User Interface Working Group.

John Burkardt
Computational Scientist

Email: jvburkardt@gmail.com

Dr. John Burkardt joined ARC in January 2017, following a research position at Florida State University, where he also taught classes in Scientific Communication, Scientific Programming, Finite Element Methods, and Discrete Algorithms. At VirginiaTech, he has given introductory workshops on parallel Matlab, OpenMP, and MPI, and guest lectures in CMDA 3634 on using OpenMP, MPI and CUDA on ARC facilities. He is familiar with the problem of legacy codes written in Fortran, and techniques for accessing them in their original form, or when all else fails, of translating the text into an equivalent form in a modern language.
