My work investigates neural coding of complex visual information. Human face perception is of special interest to me because faces convey critical social and emotional signals and because our relatively advanced understanding of face perception mechanisms makes face perception a prime window for addressing issues related to visual coding, more broadly. My lab combines techniques drawn from the domains of psychophysics, functional brain imaging, and machine learning. Results from my lab have yielded insights regarding the nature of visual processing that contributes to our impressive face categorization abilities, the corresponding cortical substrates, and the dynamics of information flow between cortical regions. The overall picture emerging from this work shows the selective, constructive, and dynamic nature of neural coding for visual information.
