Research Interests:

Cognitive Neuroscience of Visual Object Understanding:

Posters:

When we gaze upon a complex object and understand its shape what is the nature of the neural representation underlying this understanding? I am currently conducting functional imaging experiments (fMRI) under the direction of Dr. Irving Biederman at the USC Image Understanding Laboratory. These experiments are designed to shed light on the nature of this neural representation of objects. Please click on the above images to download posters on this research.

Automated Large-volume Brain Imaging:

I also am working with Harvard University researcher Jeff Lichtman to develop an Automatic Tape-collecting Lathe Ultramicrotome (ATLUM) for mapping the synaptic circuits of the brain. More information on that project can be found at: http://www.mcb.harvard.edu/lichtman/ATLUM/ATLUM_web.htm
