Network dynamics behind diverse intelligence
Research
Human cognition is dynamic, and its underlying brain activity is unstable. Thus, neural fluctuations should be essential for human intelligence and its development, while atypical brain dynamics should underpin neuropsychiatric conditions, including autism, schizophrenia and epilepsy. We pursue this framework and investigate biological mechanisms that link large-scale brain network architecture, global/local neural dynamics and typical/atypical cognition. We aim to utilise this research to understand diverse human and artificial intelligence.

Biography
After medical training in The University of Tokyo (M.D., 2007) and its hospital, I completed a Ph.D. in the lab of Professor Yasushi Miyashita in the same university as a JSPS Research Fellow (2013). I conducted post-doctoral research with Professor Geraint Rees in University College London under JSPS and Marie-Curie Research Fellowships, respectively. In 2018, I was appointed Deputy Team Leader for the Miyashita lab in the RIKEN Center for Brain Science. I launched my lab in IRCN at UTokyo as an Associate Professor (UTokyo Excellent Young Researcher Program) in April 2020. In 2025, I was promoted to Professor in IRCN at UTokyo. Other career awards include the NeuroCreative Award and RIKEN Excellent Achievement Award.
