I am an assistant professor at the University of Victoria, where I direct the Visual Interaction Design (VisID) research group. My research is in the areas of human-computer interaction, visualization, and computer-supported cooperative work. I design and evaluate visualization and interaction techniques that allow people to effectively analyze data and make decisions. My research applies to a wide variety of areas, including the sciences, medicine, and engineering. I am particularly interested in designing visualization techniques based on human perceptual capabilities, as well as designing for multiple co-located users (collaborative visualization).
