Research My research interests are the various aspects of scientific and information visualization. The visualization process involves aspects from many disciplines such as Human Computer Interfaces (HCI), Computer Graphics, Psychology, High Performance Computing, Parallel Programming, Grid Computations, Virtual Reality and Computational Geometry to name just a few. My main focus in recent years has been rapid isosurface extractions from large datasets with remote visualization in mind using desktop computers. Isosurface extractions pose unique challenges, which derive from the fundamental premise that the value of the isosurfaces is not known a-priori. As such, there is only a limited amount of pre-processing that can be done. Furthermore, when the user changes the isovalue, previously extracted geometry becomes obsolete. Recently I started working on issues involving information visualization and in particular visual representation of network events to help improve decision making in the event of network intrusion.
