Descrierea postului

Department of Biology at the Faculty of Science, University of Copenhagen is offering a PhD position in Biology commencing 01.02.2025 or as soon as possible thereafter.Description of the scientific environmentThe Andersen-Colombani group at the Department of Biology, University of Copenhagen, is recruiting a PhD to work on a 3-year project aiming at understanding the mechanisms coupling mechanical cues with SC-driven adaptive responses and pathologies using the Drosophila midgut as a model system. The position is available to start on 1 February 2025 or as soon as possible thereafter. The group is housed in the section of Cell and Neurobiology at the Department of Biology (https://www.biocenter.ku.dk/).Project DescriptionAdult tissues with high turnover rates, such as the intestine, depend on stem cells (SCs) to provide a continuous source of differentiated cells to maintain tissue homeostasis. To maintain intestinal homeostasis and gut barrier function, a complex signalling network ensures that cell loss is tightly coupled with ISC-dependent proliferation. In the past decades, an immense effort in the field has successfully identified many short and long-range signals involved in the adaptation of adult gut homeostasis to environmental biochemical cues. However, it is becoming increasingly evident that biomechanical stimuli, such as shear stress or swellings of the lumen, can modify intestinal SC (ISC) divisions and specification. The Drosophila midgut has emerged as a powerful model studying SC-driven processes in adult tissues. The project advertised here aims at studying how mechanical cues are integrated by the intestinal stem cell (ISC) niche to control ISC proliferation, differentiation, and gut homeostasis. The proposed project uses a combination of live imaging on ex vivo gut explants to monitor force-dependent effects on cell-cell rearrangements and cell topology changes and lineage tracing to evaluate force-dependent effects on ISC divisions and fate decisions. RNAis will be used to known down candidate genes in different populations of the stem cell niche, and effects on force-dependent cellular and tissue-scale adaptive responses will be evaluated.We are looking for highly motivated individuals with an MSc degree in Biology and with prior experience in fly physiology, confocal imaging, and genetics.Our group and researchOur group, which is currently composed of three postdocs, two PhD students, and three master students, is embedded in the vibrant and international environment of the section of Cell and Neurobiology, where we share fly and imaging facilities with two other Drosophila groups. The projects in the team are centered around understanding the mechanisms underpinning ISC migration, proliferation, and fate determination during homeostasis, regeneration, and disease.Principal supervisors:Dr. Ditte Andersen, Department of Biology, Cell and Neurobiology section, ditte.andersen@bio.ku.dk, Direct Phone: +45 27 85 30 22Dr. Julien Colombani, Department of Biology, Cell and Neurobiology section, julien.colombani@bio.ku.dk, Direct Phone: +45 27 84 76 66.Qualifications needed for the regular programme
