Areas of specialization	Visual psychophysics Cognitive Neuroscience Cognitive ergonomics
Laboratory/research office	Perceptual and cognitive brain information processing laboratory We live adaptively by getting information about the outer environment through our senses, processing the information in our brain, and outputting an appropriate action. The aim of our laboratory is to reveal the mechanisms of the perceptual and cognitive processes using virtual reality and functional brain imaging techniques.
Current research topics	Psychophysical study of three-dimensional perception brain function study using decoding technique with brain functional imaging
