Researcher (Postdoctral Scholar) in Developmental Neurobiology Unit (Masai Unit)

The Okinawa Institute of Science and Technology Graduate University (OIST; see is a dynamic new graduate university of science and technology in Okinawa Prefecture, Japan. The university is located on 85 hectares of protected forestland overlooking beautiful shoreline and coral reefs. The campus is striking architecturally, and the facilities are outstanding (OIST campus video tour). There are no academic departments, which facilitates multidisciplinary research. Outstanding resources and equipment are provided and managed to encourage easy access and collaboration. English is the official language of the University, and the university research community is fully international, with more than 50 countries represented. OIST is rapidly gaining recognition in the worldwide academic community as a model for excellence in education and research.

Unit summary:

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.

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.
