Time: 2:30 PM - 3:30 PM
Location: 256 Coates Hall

Dr. Bijaya Karki, Louisiana State University


Bio:
Dr. Karki received his doctorate from the University of Edinburgh, Edinburgh, UK. Before joining the Department of Computer Science at Louisiana State University in 2003, he worked as a research scholar at the University of Minnesota (Supercomputing Institute for Digital Simulation and Advanced Computation) and also at Louisiana State University (Biological Computation and Visualization Center). He is the recipient of National Science Foudation CAREER award in 2004. He has been developing/applying a metacomputing/visualization framework to address fundamental materials problems, primarily, for important geophysical implications. He is also involved in the establishment of VLab (funded by NSF ITR).

Abstract:
Ever-larger amounts of data related to various properties of materials are routinely produced by parallel computer simulations, which are based on approaches ranging from the semi-empirical methods to the sophisticated first-principles quantum mechanical methods. The simulated data, which are time-dependent and three-dimensional in the nature, are not illuminating by themselves; gaining insight into and understanding them is, however, a nontrivial task. In order to take advantage of maximal information contained in these data, we have been developing a scalable adaptive visualization framework. Our approach aims to fulfill domain-specific needs thereby justifying the effectiveness of visualization for fundamental interdisciplinary science. In this talk, I will present our current visualization activities, which include: Multiple dataset visualization based on isosurface extraction and hardware-assisted texture mapping/clipping methods, interactive atomistic visualization at space-time multi-resolution with on-the-fly extraction/rendering of a variety of additional data needed for a complex analysis, and remote/web portal visualization with online reposition of multivariate elasticity data. While the talk will primarily focus on visualization, I will also present a quick overview of other research components.

All are welcome to attend.
