Seeking a Postdoctoral Researcher or Research Scientist


Materials Dynamics Laboratory
Photon Science Research Division
RIKEN SPring-8 Center
(Associate Chief Scientist: Alfred Baron)

Research Field

The focus of the laboratory is the dynamics of materials on meV energy scales (THz frequencies) and atomic length scales, as measured using inelastic x-ray scattering. The largest project of the lab is the design, construction and commissioning of a new and uniquely powerful beamline for inelastic x-ray scattering. It should provide unprecedented capability to measure both atomic dynamics and electronic excitations with high resolution. Other projects include investigation of phonons in multiferroics, correlated-electron materials, especially superconductors, liquid dynamics, elastic constants of materials under pressure, and development of instrumentation, especially x-ray optics.

Job title and Job description

Job Title: Postdoctoral Researcher or Research Scientist (one position)
Task content: The Laboratory has recently commissioned world-leading spectrometers for measuring atomic and electronic dynamics (~1 and ~30 meV resolution, respectively). Potential research directions include investigation of magneto-elastic coupling, correlated materials, ferroelectrics, and, possibly, liquid dynamics. Extensive off-line facilities are available, in addition to the facilities of a premier operating synchrotron (SPring-8) and free-electron laser (SACLA).


Applicants must have a doctor degree (or must be expected to receive a doctor degree until the employment). Applicants for Postdoctoral Researcher should have experience of post-doctoral research of less than 5 years. Outstanding candidates from any experimental field will be considered, but applicants with previous experience in related spectroscopic methods (IXS, INS, Raman, IR) are especially encouraged to apply. Interest and/or experience in development of new x-ray techniques and instrumentation will be regarded positively.

Work location

RIKEN SPring-8 Center, RIKEN Harima Campus
1-1-1 Kouto, Sayo-cho, Sayo-gun, Hyogo 679-5148, Japan

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 (5 years for Postdoctoral Researcher).
  2. RIKEN may adjust the above maximum period of renewability based on a) the employee's abilities, workload 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 that time.
  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).

Salary will be commensurate with qualifications and experience. Commuting and housing allowances will be provided. Social insurance will be applied. The position requires membership in the RIKEN Mutual Benefit Society (RIKEN Kyosaikai). 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 is promoting a Gender Equity Program by taking various measures to create a workplace where both men and women are fully able to apply their talents and abilities. When applicants are judged to be equally qualified on the basis of fair and impartial criteria, women applicants will be given preference.

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 applying for the MEXT Grants-in-Aid for Scientific Research (Kakenhi).

Application and required documents

Please send the following documents to the e-mail address given below:

  1. Complete CV (including a facial photograph)
  2. List of research achievement and publications (peer-reviewed papers, oral presentations at conferences)
  3. Statement of research interests
