Postdoctoral research scientist position (Computational neuroscience)
Hiroyuki Nakahara Lab. for Integrated Theoretical Neuroscience
Center for Brain Science (W19072)


Laboratory for Integrated Theoretical Neuroscience (Laboratory head: Hiroyuki Nakahara)

Research field

We are interested in understanding the computational principles that underlie the way neural systems realize decision-making and adaptive behavior; in particular, reward-based decision-making and learning (reinforcement learning), and social decision-making and learning. For more information, please see our HP: .

Research Scientist in computational neuroscience: 1 position

Job description

We seek a highly motivated postdoctoral fellow to work on human fMRI experiment. We aim to elucidate neural mechanisms and computations for decision-making and learning, often together with social functions. Examples of our current interest include (but not limited to):

  • • REINFORCEMENT LEARNING: valuation, decision-making and learning, interacted with emotions; in relation to structural and representational learning, or model-based learning; with inference on environments and/or deep learning; coupled with meta-cognition and/or mental accounting (neuroeconomics)
  • SOCIAL LEARNING AND DECISION MAKING: decisions and learning with theory of mind; learning models of others' minds and associated inferences; empathy and decision making with inference of others' emotions; structural learning for rich repertoire of other individuals' decision-making

To validate our proposals and models, a prospective fellow is expected to use simulations in comparison to existing data, which is likely complemented with our own crowdsourcing or behavioral experiments. In addition, s/he is expected to be willing to collaborate with experimental investigations that other scientists conduct (e.g., in-house fMRI).


The candidate should possess a doctoral degree in computational neuroscience or a relevant field. Robust experience and demonstrated achievement in the research related to our interest is expected. Proficiency in programming (e.g., MATLAB) is expected.
