Seeking a Research Scientist (CS1901)


Laboratory for Chromosome Segregation
RIKEN Center for Biosystems Dynamics Research
(Team Leader: Tomoya Kitajima)

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.

Torpor (e.g. hibernation, daily torpor, or dormancy) is a natural energy-saving mechanism that actively produces a hypometabolic state upon biological crises. BDR has started a center-wide project, which investigates, manipulates, and engineers quiescence for facilitating future applications, through collaborative actions of BDR laboratories including us.

The Laboratory for Chromosome Segregation is seeking to recruit a motivated research scientist who carries out researches including the ones that contribute to the center-wide project. Our major interest includes how oocytes establish and maintain a dormant state in fetal and adult ovaries to support a long-term proteostasis that prevents precocious reproductive aging such as egg aneuploidy. Studies would take advantage of developmental, cell, and molecular biology techniques, using mice as a model, as well as unique skills and backgrounds of the appointed research scientist. Candidates who are motivated to carry out an interdisciplinary study in the center-wide collaborative environment are strongly encouraged to apply.
