What are the mechanisms that generate our rich and stable visual world from the
highly ambiguous and ever-changing light pattern falling on the retina? How do
complex interactions between local and global levels of processing, and their
dependence on factors such as grouping and Gestalt, shape visual perception?
Why do we experience the visual world the way we do?
In our lab, we investigate these and related
questions, primarily in the realm of spatial vision. For example, to understand the role of
perceptual organization and context in
visual perception, we study crowding, masking, and visual search using a
variety of psychophysical procedures. We extend traditional performance
measures by directly quantifying perceptual experience using novel
appearance-based methods, such as analyzing observer drawings of
gaze-contingent peripheral stimuli.
Finally, we foster connections between scientific and artistic explorations of
the visual world, demonstrating how vision science and art can mutually enrich
