Seeking a Research Scientist or Postdoctoral Researcher (26-1435) Part-time

Research Scientist Or Postdoctoral Researcher

Brain-Body Interaction RIKEN ECL Research Team, RIKEN Center for Brain Science (To be established: Dec. 1, 2026) (RIKEN ECL Team Leader: Tomoe Ishikawa)

Our laboratory aims to understand how the brain controls other organs and, through these interactions, regulates physiological functions. In particular, we seek to elucidate how interactions between the nervous and immune systems influence the host response to pathogen infection. Ultimately, we aim to determine whether immune responses can be regulated by manipulating neural activity.

Job Title

Research Scientist or Postdoctoral Researcher 1-2 position(s)

• Research Scientist is defined as those with a doctoral degree more than 5 years.
• Postdoctoral Researcher is defined as those with a doctoral degree of 5 years or less.

Job Description

The candidate will conduct research aimed at understanding the brain–body and neuroimmune interactions that regulate physiological functions. Specifically, the candidate will combine mouse models with approaches in biology, neurophysiology, and immunology to investigate how social behavior influences subsequent responses to pathogen infection. The candidate will also seek to identify the neural circuits and brain–body interactions underlying these observed phenomena. In addition to conducting experiments using established experimental paradigms in the laboratory, the candidate will develop and test hypotheses based on experimental findings.

The job description may be changed during the contract period or upon contract renewal to the extent described above.

Qualification

We are interested in understanding how interactions between the brain and peripheral organs regulate physiological functions and are seeking highly motivated researchers with experience in neuroscience techniques, such as behavioral analysis, optogenetics, chemogenetics, and in vivo or in vitro electrophysiological recordings, as well as in molecular biology and/or immunology. Experience with stereotaxic surgery in rodents, tissue sectioning, and/or staining is also preferred. Applicants are expected to hold a Ph.D. in a relevant field, such as neuroscience, biology, veterinary medicine, or medicine. Candidates should also be comfortable working in an international research environment in which English is the primary language of communication.
