Dr. Kenny Gruchalla leads the visualization efforts in the Computational Science Center at NREL. His current research is focused on developing interactive scientific visualization techniques that provide tools for finding meaning in increasingly large and complex data. Kenny has more than 15 years of professional experience in scientific programming and scientific visualization, spanning several scientific disciplines, including aerospace, geophysics, molecular biology, and environmental engineering. Dr. Gruchalla's dissertation work focused on the development of a general framework to define multi-scale, multi-variate, non-Cartesian regions of interest in large-scale turbulent flow data. His master's thesis research evaluated scientific workflows in immersive virtual environments. His current research interests include scientific visualization, immersive visualization, GPU computing, topology-based feature extraction, human-computer interaction, and physics-based modeling.
