Early-career Researchers
RIKEN International Program Associate (IPA)
IMS accepted four international students as RIKEN International Program Associates (IPA). Under this IPA program, IMS lab heads host international students from collaborating graduate schools and supervise their Ph.D. program as Joint Supervisors. The students receive a daily living allowance and housing costs for up to a maximum of three years. The IPA students who studied at IMS in 2025 were
- Yali Xu
- (Nanjing University, China)
- in the Laboratory for Cellular Function Conversion Technology
- Jan Peter Pack
- (McGill University, Canada)
- in the Laboratory for Human Disease Models
- Zhizhen Qin
- (Institute of Science Tokyo, Japan)
- in the Laboratory for Transcriptional Regulation
- Fatma Ramadan Shaaban Ramadan Elsharkawy
- (Institute of Science Tokyo, Japan)
- in the Laboratory for Transcriptional Regulation
- Lars David Michael Pennings
- (University of Melbourne, Australia)
- in the Laboratory for Transcriptome Technology
RIKEN Junior Research Associate (JRA) Program
The Junior Research Associate Program was launched in 1996 to encourage young scientists with fresh ideas and youthful enthusiasm to collaborate with, and learn from, senior scientists with years of experience. This program provides part-time positions at RIKEN for young researchers enrolled in university Ph.D. programs. The JRA program serves the dual purpose of fostering the development of these young scientists while also energizing RIKEN with their innovative thinking. This year, 28 JRA students studied in IMS.

RIKEN Student Researcher (RSR) Program
The RIKEN Student Researcher Program was newly established in 2021 in order to foster excellent researchers. In this program, students enrolled in the Master's and Doctoral courses are hired on a "part-time" basis, and researchers from RIKEN and domestic graduate schools work together to provide research guidance to students in order to help them obtain their degrees. This year, 8 RSR studied in IMS.

RIKEN Special Postdoctoral Researcher (SPDR) Program
RIKEN's Special Postdoctoral Researcher Program was instituted to provide young and creative scientists the opportunity to be involved in autonomous and independent research in line with RIKEN objectives and research fields. The positions are competitive, but if selected, researchers receive salaries and research budgets (1 million yen) from RIKEN and they are able to conduct their research at one of its laboratories. This year, 11 postdocs conducted their research at IMS through the SPDR program.
