This is me testing a baby and at a party

 My main research interests involve studying the development of vision in normal infants, the consequences of visual deprivation during infancy, and recovery from amblyopia.

 The normal development of vision. We are investigating developmental changes in visual abilities such as the perception of form and motion. The results to date suggest that aspects of vision requiring more steps of cortical processing are slower to develop than those requiring fewer steps of cortical processing.  

The visual development of children treated for cataracts. To learn more about the importance of early visual experience on the development of vision, we have been studying an unusually large cohort of children who were deprived of normal visual input until they had surgery to remove dense central cataracts and were fitted with contact lenses. Studies in progress involve visual acuity, and the perception of form and motion. Deficits in these patients suggest that visual outcome is influenced by when the deprivation began, how long it lasted, and whether it occurred in one or both eyes. Moreover, the effects of early visual deprivation often differ for aspects of vision mediated by the primary visual cortex versus those mediated by higher cortical areas.

Recovery from amblyopia. We have established a collaborative research network of six labs from around the world in order to (1) study ways to induce recovery from amblyopia and (2) use amblyopia as a model system to re-examine critical periods and developmental changes in plasticity.

Overall, the results will provide insights into the developmental mechanisms driving changes in visual abilities. The results will also have important clinical implications for understanding treatment protocols leading to an optimal visual outcome and may also provide a basis for new approaches to rehabilitation.
