Seeking two Research Scientists or Postdoctoral Researchers (BCI2001)


Laboratory for Brain Connectomics Imaging
RIKEN Center for Biosystems Dynamics Research
(Team Leader: Takuya Hayashi)

Research Field

The Center for Biosystems Dynamics Research (BDR) views the functions of molecules, cells, and organs that support all life stages of organisms as a dynamic system, and aims to elucidate developmental, growth and aging phenomena as well as apply their findings to develop regenerative medicine and diagnostics, thereby contributing to the extension of healthy life expectancies.

The Laboratory for Brain Connectomics Imaging, led by Dr. Takuya Hayashi, is recruiting research employees to carry out a new theme. The Hayashi laboratory focuses on comparative neuroscience, population & individual neuroscience (aging, development, sociality) in the emerging field of primate brain connectomics using magnetic resonance imaging. We develop non-invasive brain connectomics imaging technologies, including data acquisition, preprocessing, computational & statistical modeling, and databasing and sharing. We collect large amounts of in vivo data from humans and non-human primates (NHP), standardizing data into a common space by applying mathematical image processing grounded in neuroanatomical and functional correspondences. We use a 3T MRI scanner (Siemens MAGNETOME Prisma) installed in our center to achieve these goals.

We seek to understand the genesis of human behavior by associating brain structure, function, connectivity, genetics and environment. We also seek to find the mechanism of dynamics and plasticity of the connectome in relation to learning, development, aging, as well as neuropsychiatric diseases. We address questions by quantifying cortical expansion, and spatio-temporal dynamics of functional and structural connectomes of individual brain using high-quality MR imaging system. Our lab collaborates closely with David Van Essen and Matthew Glasser at Washington University in St. Louis, core members of Human Connectome Project (HCP) in USA, Henry Kennedy (Stem Cell Brain Research Institute, Lyon), Stephen Smith, Saad Jbabdi, Rogier Mars (Oxford University, Oxford), Stam Sotiropoulos (Nottingham University), Alain Dagher (MNI, McGill University, Montreal), Takashi Hanakawa (Kyoto University, Kyoto), Norihiro Sadato (NIPS, Okazaki) and others. We also collaborate with multiple R&D companies on the development of medical imaging devices, diagnostic technologies, and therapeutics. Our lab is funded by national research grants, Brain/Mind-beyond from AMED and KAKENHI from MEXT and JSPS. Lab members are encouraged to communicate and present their work in English, and to exchange research topics and technologies with others outside lab. Lab alumni currently work at major universities and research institutes.

Job descriptions

The successful candidate will investigate the organization, life span (development and aging) and evolution of brain structure, function, and connectivity in primates (humans, macaques and marmosets). He or she will analyze data of brain connectomics imaging using multi-modal and multidisciplinary approaches including neuroimage preprocessing, computational modeling, and neuroinformatics. This will entail using scripting languages for analyzing data, and writing scientific manuscripts that reveal details or dynamics of brain connectomics by comparing species and associating with behaviors, genes etc. Analysis of brain imaging data will include human and non-human primate versions of the HCP’s minimal preprocessing pipeline (MPP), Connectome Workbench, FSL, Freesurfer, Matlab. Statistical analysis will be done with Matlab, and R. Machine learning and deep learning techniques may be used for improving analysis. Brain connectomics data we use are HCP-Style high-quality, high-resolution structural MRI (T1w, T2w), resting-state and task functional MRI, and diffusion MRI, as well as lower quality or legacy data, obtained in our lab or others.


A PhD holder in the area related to the Job description. In general, those who earned a doctorate within the past 5 years will be appointed as Postdoctoral Researchers, and those who earned a doctorate more than 5 years ago will be appointed as Research Scientists. Exceptions may apply to those with an outstanding record of achievements.

Successful candidates would possess a doctoral degree and research experience in a related field. Essential skills include 1) writing scientific manuscripts and presenting own work, and 2) programming with scripting languages (e.g., Bash, Matlab, python). Desirable expertise incudes knowledge or experience in mathematics, physics, engineering, machine learning and deep learning. Prior experience with major neuroimaging tools (e.g., FSL, FreeSurfer, and HCP Pipelines and visualization tools), in magnetic resonance imaging (MRI), neurobiology, neuroanatomy is also desirable but not mandatory.

A person who can dedicate themselves to the job by communicating, coordinating and collaborating smoothly with people in and out of the laboratory.

Work location

RIKEN Center for Biosystems Dynamics Research (Kobe Campus-East-West)
6-7-3 Minatojima-minamimachi, Chuo-ku, Kobe, Hyogo 650-0047(MI R&D Center Building)

The lab is located in RIKEN Kobe campus in Kobe, Japan. The city of Kobe is located in the Western part of Japan in a unique setting between the Rokko Mountains and the Inland Sea. The city's port has historically played an important role in opening Japan up to international influence and the city retains a cosmopolitan and sophisticated air to this day. In addition to a bustling Chinatown and the more relaxed historical foreign settlement, there are a number of international restaurants, jazz bars, and hot springs. Japan's renowned public transport system also means that Kobe is within easy reach of the ancient capitals of Kyoto and Nara, which contain over 1,000 historical temples and shrines.
