| My lab studies human vision, including visual search, peripheral vision, perceptual organization, and the impact of visual clutter on task performance. We take a three-pronged approach: 1) Computational modeling (computer vision-based, ideal observers, Monte Carlo simulations, and neurobiologically-inspired); 2) Behavioral experiments; and 3) Applying our models and understanding of human vision to applications such as image compression, design of user interfaces, and design of information visualizations. | My lab studies human vision, including visual search, peripheral vision, perceptual organization, and the impact of visual clutter on task performance.
