Developmental Neurobiology Unit / Researcher (Postdoctral Scholar)

The position

Developmental neurobiology unit in the OIST has investigated the mechanism of vertebrate retinal development, especially neuronal diffrenetiation and neural circuit formation, using zebrafish as an animal model. Furthermore, the unit has also investigated the mechanism underlying photoreceptor degeneration and regeneration. Throughout these research projects, we will establish novel concepts that govern development of multicellular organisms and also contribute to understanding pathological processes involved in human eye diseases.

Information on our research is shown in our lab URL ( ).


We are searching a researcher, who will investigate either of following research topics, using zebrafish as an animal model.

1) Mechanism of retinal cell differentiation and neural circuit formation

2) Molecular and cellular mechanism of photoreceptor degeneration and regeneration

3) Role of microglia in neuronal degeneration and regeneration

We appreciate application of young motivated researchers who have worked in the field of cell and developmental biology and are willing to contribute to medical therapy for human eye genetics disease.
