Hi, I am a postodoctoral fellow in the University of Tokyo. My research interest is the intersection of Computational Neuroscience and Artificial Intelligence. During Ph.D., I worked on reliable techniques for predicting diverse individual differences from whole-brain functional connectivity using functional magnetic resonance imaging (fMRI) at ATR Brain Information Communication Research Laboratory. More recently, I am working on understanding a dynamic computation during complex decision making tasks with machine learning technique in the Oxford Centre for Human Brain Activity at the University of Oxford.
