My research is focused on perceptual issues in visualization of complex data and phenomena. We use visualization to map data (from many sources and in many forms) onto images. We then use the images to explore structures and relationships in the data, and use our new understanding of the data to support decisions. As such, I am interested in how to map raw data onto imageable data (computational geometry), how to map properties of light transport onto processed data to produce an image (computer graphics), how the visual system extracts information from images (visual perception), and how we process that extracted information to support decisions (cognition).
