My research focuses on human visual object perception and recognition. Specifically, using human neuroimaging techniques such as functional MRI, I am now investigating how 2D retinal inputs are translated into 3D depth structures, how local image features are integrated into a coherent visual object, how multiple and different visual clues are integrated, and how fragmental and incomplete visual inputs are compensated into a whole.

A fundamental challenge in visual neuroscience/psychology is to understand the processes by which the outputs of neurons with spatially limited receptive fields are progressively transformed to encode information about objects at more extensive scales. Although our visual system tends to be often explained as an analogy of camera and photographs, our visual system actually has more capabilities to solve remarkably complicated problems that are far beyond the standard camera does. Therefore, to answer the questions above is very important not only to accumulate our basic knowledge in the neuroscience and psychology fields, but also to develop novel frameworks towards the future ICTs (Information and Communications Technologies).

Recently, I am also interested in developing novel fMRI data analysis techniques. Especially, I am trying to combine brain activities obtained from different individuals into one virtual super brain and to explore the possibility of fMRI-based “wisdom of crowds” and/or “collective intelligence.”

If you are interested in these fields, please feel free to contact me and let’s collaborate together.
