Research Interests My work centers around two overarching themes: the relationship between neural activity and conscious visual perception, and the role that visual experience plays in determining the course of visual development. I focus on early and mid-level visual processes that underlie the perception of objects and the layout of surfaces in the environment. 

Human neuroimaging. In adults my group relates perceptual judgments and performance to neural activity through a novel imaging approach that combines the high temporal resolution of electroencephalography (EEG) and magnetoencephalography (MEG) with the high spatial resolution of functional Magnetic Resonance Imaging (fMRI).  What distinguishes our approach to neuroimaging from that others is the application of computational methods from the field of non-linear systems analysis. To fundamentally advance this work, I collaborate with mathematician Dr. R.T. Miller on the development of new analysis methods for non-linear systems. 

Human visual development. The development of EEG-based methods by my group has also been driven by my interest in visual development.  Direct neural recording from the developing human brain provides a view on development that is unhindered by immaturities in behavioral and cognitive systems. I learn about vision and its relationship to the brain by watching how structure and function evolve during normal development, and how they break down when visual experience is abnormal.  Development and disease are powerful natural occurring experiments that often provide insights that are not apparent when studying the intact normal adult. To further this work, I collaborate with pediatric ophthalmologists both at Smith-Kettlewell and at the Royal Liverpool ChildrenÕs Hospital and with pediatricians at Stanford University.

Neuroimaging methods development. Finally, to overcome the indirect nature of EEG and fMRI recordings,  I collaborate on the development of novel imaging modalities. I work with Dr. Matteo CarandiniÕs group at Smith-Kettlewell which uses voltage-sensitive dyes to record  from the exposed cortex of experimental animals.  This imaging modality has a spatial resolution of 100 microns and millisecond temporal resolution.  Methods of non-linear analysis that we have developed for use with the human EEG are directly transferable to dye imaging and offer significant benefits over traditional linear methods for understanding neural computations.  These recordings are based on the same underlying mechanism as EEG, but they can be obtained at a much finer spatial scale.  In a new collaboration with Dr. Peter BandettiniÕs group at NIMH, I am applying signal processing methods developed for the EEG to Ōneural current imagingĶ --- the direct detection of neural activity using an MRI scanner.  If successful, this effort will lead to an imaging modality with both high temporal and high spatial resolution.

National Institutes of Health/National Eye Institute

Normal and Abnormal Development of Spatial Vision

This project will study the neural mechanisms of texture and motion based segmentation as basic inputs to object processing in normal adults. The project uses frequency-domain non-linear analysis of EEG and MEG recordings, combined with fMRI.  We will also study the role of normal binocular vision during development on segmentation performance in adult patients with strabismus.

Form and Motion Integration

This project studies the integration of local estimates of motion direction and orientation into global patterns of optic flow using EEG and fMRI.  Integration mechanisms will be studied in normal adults and in adults with amblyopia, focusing on processing mechanisms and the role of visual attention in modulating sensitivity. The normal development of these integration mechanisms will also be studied in human infants.
