POSTDOC_Species-Specific ADAT Function in Cortical Development_061_JG - H/F

INSERM; Illkirch-Graffenstaden; Sur place; EUR 42 000 - 54 000; Plein temps

Résumé du poste

INSERM’s Institute of Genetics and Molecular and Cellular Biology (IGBMC) in Strasbourg, France, invites a postdoctoral researcher to study species-specific ADAT functions in neural development using human iPSC- and mouse ESC-derived models. The 30-month position focuses on translational control during cortical development and organoid systems carrying ADAT2/ADAT3 variants. Under Dr.

Juliette Godin and Dr. Efil Bayam, you will combine stem cell biology with genomics analyses, present at

Qualifications

• Ph.D. in Cell Biology, Molecular Biology, Developmental Biology, Neuroscience or related field.
• Experience with human iPSC culture and/or 2D/3D neural differentiation protocols.

Responsabilités

• Generate and characterize human iPSC-derived 2D cortical neural stem cells, neurons and 3D cortical organoids carrying pathogenic ADAT2/ADAT3 variants.
• Assess cellular phenotypes (proliferation, cell cycle, progenitor identity, neuronal maturation, synaptic integration) using immunofluorescence, EdU/pulse-chase labeling and functional assays (MEA, calcium imaging).
• Analyze human mim-tRNA-seq and ribosome profiling data to characterize species-specific tRNA and translational programs.
• Present findings at meetings and conferences; contribute to manuscript writing and project reporting; supervise students.

Description du poste

Le Poste

We are looking for a highly motivated postdoctoral researcher to join the “Physiological and Pathological Mechanisms of Cortical Development” team led by Dr. Juliette Godin at the Institute of Genetics and Molecular and Cellular Biology (IGBMC) in Strasbourg, France. The Godin lab is a recognized expert in translational control during cortical development. The selected candidate will work under the direct supervision of Dr. Efil Bayam (CRCN Inserm), in the framework of the ANR-funded project SpeaDAT, which investigates the species-specific mechanisms of ADAT tRNA deaminase complex dysfunction in brain development. The postdoctoral researcher will study species-specific ADAT functions in progenitors and neurons and characterize impact of ADAT dysfunction on tRNAs and translational programs using human iPSC- and mouse ESCs -derived models, including 2D cortical neural stem cells/neurons and 3D cortical organoids carrying ADAT2 and ADAT3 pathogenic variants. This 30-month position is well suited to a recently graduated PhD experienced with human iPSC culture and/or 2D/3D neural differentiation protocols.

L’Inserm est le seul organisme public français entièrement dédié à la recherche biologique, médicale et en santé des populations.
