Summary of Research Interests and Accomplishments
My current research focuses on Computer Graphics, and specifically Scientific and Medical Visualization. After resolving different aspects of representing and rendering regular and irregular point-based datasets during my dissertation research, I have been investigating real-time rendering and CT reconstruction using modern GPU hardware. I have also developed a novel interaction paradigm for real-time color gamut manipulation targeted to color professionals and artists. My past research spans to Parallel and Distributed Architectures and the development of programming tools targeted to these systems.
