Postdoctoral Research Scientist in human fMRI: 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; 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

We often drive our studies by the understanding and knowledge of computational neuroscience and use advanced methods to analyze data, such as model-based analysis and multi-variate pattern analysis.


Applicants should have (or be expecting to receive, before the work start date here) a Ph.D. in neuroscience or a related field. Robust experience and demonstrated achievement in human fMRI or a related field (e.g., neurophysiology) is expected. Proficiency in programming (e.g., MATLAB) is necessary.

Work location

Branch and address
RIKEN Wako (2-1 Hirosawa, Wako, Saitama 351-0198)

Salary and benefits

  1. A one-year fixed-term employment contract, renewable based on evaluation, to a maximum of the end of the fiscal year (March 31) in which the employee completes 7 years of employment.

RIKEN may adjust the above maximum period of renewability based on a) the employee's abilities, work load at the time of contract completion, performance and work attitude and b) the continuation of the employee's center, laboratory or project and RIKEN's management situation and budget at the time. In principle, employment contracts will not be renewed for individuals older than 65 years.
  3. The employee's period of fixed-term employment cannot exceed 10 years from the initial date of hire (or 10 years from April 1, 2013 for fixed-term employees already at RIKEN prior to this date).

The salary system is annual and will be commensurate with qualifications and experience. Commuting and housing allowances will be provided. Social insurance will apply.
Mandatory membership in the RIKEN Mutual Benefit Society (RIKEN Kyosaikai) is required.
Days off include public holidays, New year's holidays (Dec. 29 – Jan. 3), and RIKEN Foundation Day.
These and other provisions are in accordance with RIKEN regulations.
※RIKEN promotes a Gender Equity Program by taking various measures to create an equitable workplace where both men and women are able to give full rein to their talents and abilities. When the abilities of candidates are judged to be equivalent through a fair and impartial evaluation process, preference will be given to females.

*Also, eligible for an exemption from repayment for category 1 scholarship loans provided by the Japan Student Services Organization before fiscal year 2003, and eligible for applying for MEXT Grants-in-Aid for Scientific Research (Kakenhi)


Applicants are also encouraged to apply for JSPS or other external funds.
