The human brain has many long-range connections throughout white matter, which are essential for communication across distant brain regions having different functions. Recent progress on diffusion MRI and fiber tractography opens an avenue for identifying white matter fascicles in the living human brain. I think that an understanding of the tissue and network properties of white matter is crucial for elucidating how the human brain is able to process massive information throughout efficient communications across distant regions.

Using diffusion MRI and fiber tractography, I am studying the long-range white matter fascicles and examining the tissue properties along fascicles in relation to behavior, health and disease. In particular, I am focusing on the white matter fascicles involved in visual processing and multi-sensory integration. I am also developing the analysis method to improve the performance of fiber tractography.
