Postdoctoral Researcher 1 position

Job description

The successful candidate will conduct research to elucidate the core molecular mechanisms underpinning rice root invasion by diverse beneficial arbuscular mycorrhizal fungi. As Magnaporthe oryzae adopts an endophytic life-style in rice roots, related to arbuscular mycorrhizal fungi, it will serve as a genetically tractable comparative system. The hire will be expected to independently design, perform and interpret experiments, including plant and fungal cultivation, inoculation and colonization assessment by standard and confocal microscopy and a wide range of molecular techniques, including transcriptome analyses on an organ or single cell level. The dissemination of findings at national and international conferences is a core component of the job.

The job description may be changed during the contract period or upon contract renewal to the extent described above.

The candidate should possess a doctoral degree in molecular genetics of plant or fungal biology with a preference for plant-microbe interaction. A strong component on plant and/or fungal transcriptomics and relevant bioinformatics is preferred.
