The Department of Biology, Section of Microbiology invites applicants for a PhD fellowship to study social interactions in the plant root microbiome.
Start date is (expected to be) 1 August 2024 or as soon as possible thereafter.
The project
Novel strategies for eco-friendly and sustainable food production seek to explore and exploit the potential of the plant microbiome to promote growth, acquire nutrients, and induce resistance against pests and pathogens. Yet, we lack a fundamental understanding of the ecological factors controlling the establishment of a beneficial plant microbiome. Hence, we seek to test the ecological and evolutionary role of microbe-microbe interaction in the assembly and maturation of complex plant root microbiomes.
This project investigates the role of microbial interactions as key drivers for microbiome composition and activity, specifically focussing on interspecies cooperation/competition and the resulting priority effects. We work with the overarching hypothesis that microbial communities are composed of collaboromes, rather than independent species, that are characterized by being microscale focal points of interdependent bacteria showing essential microbe-microbe interactions. The emergent properties of these collaboromes present many beneficial consequences for plant growth and health.
The experimental design of this project goes beyond simple co-occurrence in bulk microbiome samples. Instead, it focuses on co-occurrence network analysis on microscale samples, which is complemented with detailed co-localization analyses to identify putative interactions. Finally, selected identified putative interactions are experimentally validated in simple microcosm experiments.
Who are we looking for?
We are seeking a highly motivated and ambitious individual with good interpersonal and communication skills. Highly desired candidates will have a solid theoretical background in plant-microbiome interactions. As well as practical experience with techniques in microbiology and molecular biology. A strong interest in bioinformatics and/or bioimaging is also considered advantageous.
Applicants should hold an MSc degree in Plant Biology, Microbiology, Bioinformatics, Biochemistry, Biotechnology, or similar with good results and good English skills. As criteria for the assessment of your qualification emphasis will also be laid on previous publications (if any) and relevant work experience. The MSc degree must be awarded prior to the employment date.
Our group and research- and what do we offer?
The PhD fellow will be part of the Section of Microbiology, headed by Prof. Søren Sørensen. His research group focuses on social interactions in microbial populations in in-vivo systems such as soils, plants, animals, and humans. The section houses state-of-the-art both culture-dependent and culture-independent experimental infrastructure that enables us to examine how microbes interact at a scale that is relevant for such small organisms and study the roles of the individual species in these interactions. To do so we use techniques such as high throughput sequencing, flow cytometry, ultra-high resolution bioimaging, confocal microscopy, and microbial reporter systems, combined with the reductionist synthetic community approaches, allowing in-depth investigation of the microbe-microbe or host-microbe interactions mechanism.
The Section offers a highly diverse and inclusive environment consisting of ≈35 researchers who specialize in microbial community interactions, mobile genetic elements, horizontal gene transfer, and the early life human microbiome. The group has gained an international reputation for applying a combination of bioinformatics and molecular biology approaches to address research questions of ecological, clinical, and biotechnological interest, which lie at the intersection of computational biology, genomics, and bacterial evolution.
The group is a part of the Department of Biology, Faculty of SCIENCE, University of Copenhagen. We are located in Copenhagen.
Principal supervisor is Professor Søren Sørensen (sjs@bio.ku.dk ), Section of Microbiology, Department of Biology. The student will be co-supervised by Dr. Ke Tao (ke.tao@bio.ku.dk).
The PhD programme
Qualifications needed for the PhD programme
