About the positionWe invite applications for a Researcher position at the Department of Biosciences The position is for a period of 3 years. Starting date no later than 01.04.2027 with a preferred starting date around the 21st of January. Place of work is the Department of Biosciences at the Life Science Building, Forskningsparken, Oslo. Project descriptionApplicants are invited to apply for a 3-years position as Researcher in Fish Immunology / Microscopy to be based at the Department of Biosciences of the University of Oslo. This role contributes to the ERC-funded starting grant project “Fish-S.H.I.E.L.D.” starting on April 1st 2025, which aims to investigate the fish branchial cavity immune surveillance system and its importance for the fish defense against infectious diseases in aquaculture. More about the positionThe successful applicant will join Julien Resseguier’s “Spatial Immunology & Nanomedicines” group and become a key member of the Comparative Immunology team at the Department of Biosciences. The project “Fish-S.H.I.E.L.D.” builds on the recent discovery of a complex lymphoid organization in the fish branchial cavity, which includes the “Amphibranchial Lymphoid Tissues (ALT)” and the “Interbranchial Lymphoid Tissues (ILT)” in the gills, and the Nemausean Lymphoid organ (NELO), revealing the branchial cavity as an important region of the fish immune system. https://www.science.org/doi/10.1126/sciadv.adj0101 https://www.frontiersin.org/journals/immunology/articles/10.3389/fimmu.2021.769901/full The sustainability of aquaculture, important for our food security, is severely challenged by infectious diseases. Whereas the branchial cavity is particularly relevant for fish health and welfare in aquaculture, much remains to be done to understand its defense mechanisms. The main goal of the project is to characterize the newly discovered branchial cavity immune surveillance system to harness its potential against infectious diseases in aquaculture. The project objective will use the zebrafish model to 1) Characterize the gill lymphoid tissues and tonsil-like organ. 2) Decipher the rules of antigen sampling, 3) Characterize the developmental framework. 4) Study the involvements in immune responses to infection and vaccines. This will then serve as a guide for investigations in Atlantic salmon and other fish species relevant for aquaculture. The project will involve characterizations of immune functions using infection models and nanotechnologies, immunohistology, transcriptomics, antibody assays, and advanced 3D microscopy. For this, a lightsheet microscope dedicated to the imaging of cleared samples is being acquired, as well as a workstation for VR-assisted image analysis. This represents an unique opportunity in Norway. We seek a highly motivated Researcher that will be primarily involved in the transcriptomic aspects of the project and microscopy. Tasks will mainly focus on using ScRNAseq and 3D high-resolution imaging to investigate the branchial cavity immune system with an emphasis on characterizing immune cell population and the gene expression of markers of relevant immune functions. The project will involve experiment with both zebrafish and Atlantic salmon. What skills are important in this role?The Faculty of Mathematics and Natural Sciences has a strategic ambition to be among Europe's leading communities for research, education and innovation. Candidates for these fellowships will be selected in accordance with this, and expected to be in the upper segment of their class with respect to academic credentials. Required qualifications: Applicants must hold a degree equivalent to a Norwegian doctoral degree in Fish Immunology, Cell Biology, Molecular Biology, or a related discipline. Doctoral dissertation must be submitted for evaluation by the closing date. Only applicants with an approved doctoral thesis and completed defence are eligible for appointment. Fluent oral and written communication skills in English.
