Seeking a few Research Scientists or Postdoctoral Researchers (PB2202)


Laboratory for Physical Biology
RIKEN Center for Biosystems Dynamics Research
(Team Leader: Tatsuo Shibata)

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 Physical Biology is recruiting research employees to carry out a new theme. In the laboratory, we are studying mechanisms giving rise to the emergence of order in multicellular organisms from the viewpoints of physical and mathematical sciences. In particular, we have been working on chemotaxis, cell polarity, cell motility, collective motion in tissues, axis formation in embryos, chirality of cells and tissues. For these problems, we develop mathematical model, perform analysis of experimental data, and compare them to extract essential aspects. We are actively conducting collaborations with experimental groups. We are seeking highly motivated and qualified researcher who want to challenge questions in biology using integrated approaches with mathematical theory and quantitative analysis of experimental data. Our recent publications can be found from our web page (Laboratory for Physical Biology website).
