Hi, I am a Project Associate Professor at the Research and Development Center for Large Language Models at National Institute of Informatics. My research interest lies at the intersection of Artificial Intelligence and Cognitive Computational Neuroscience. During my Ph.D., I worked on reliable techniques for predicting diverse individual differences from whole-brain functional connectivity using functional magnetic resonance imaging (fMRI) at the ATR Brain Information Communication Research Laboratory. After obtaining my degree, I have been working on understanding dynamic computations during complex decision-making tasks using machine learning techniques at the Oxford Centre for Human Brain Activity at the University of Oxford, and Department of Psychology at the University of Tokyo. More recently, I investigated the connection between generative AI and the human brain at Osaka University.
