Research Interests:

Update: I have recently graduated from USC and am doing a Post Doc at Harvard University in the laboratory of Jeff Lichtman.

My main research interest is exploring how the brain represents the visual world. Specifically I have been conducting fMRI experiments, under the direction of Dr. Irving Biederman at the USC Image Understanding Laboratory, designed to test how multi-object scenes are represented in the later stages of the ventral visual stream. A pdf copy of my PhD thesis can be downloaded here:

PhD Thesis: EXPLICIT ENCODING OF SPATIAL RELATIONS IN THE HUMAN VISUAL SYSTEM: EVIDENCE FROM FUNCTIONAL NEUROIMAGING [PDF download]

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

Additional interests: I am also actively researching methods for whole brain preservation and am calling for scientists in general to do more research in this important area. For more information see my other website: http://www.brainpreservation.org
