  • Missions and Goals

    Finding something solid, but new, different and exciting

    Aiming to hit between the eyes of others.

    Connecting scientific findings with applications

    Linking the findings in cognitive neuroscience and experimental psychology with things that can help society

    Training our skills and mind through cutting-edge researches

    Through working on cutting-edge researches together, we learn not only skills of cognitive neuroscience, but also way of thinking.

    I am looking for a research fellow and graduate students working with me!

    Ryo Kitada,

    Principal Investigator, Nanyang Associate Professor

    I am a cognitive neuroscientist who has been fascinated by many questions on mind and brain, such as how our mind and brain work, how they develop and how they become atypical.


    I completed my PhD in Neuroscience at Kyoto University and then worked as a postdoctoral fellow and research associate under supervision of Dr. Susan J. Lederman. After spending 9 years at an assistant professor at National Institute for Physiological Sciences (NIPS) Japan, I have started this lab from January 2017.
