PhD Fellowship in Plant Science

We are seeking a candidate to fill a fully funded PhD position for a period of 3 years in the Insect-Microbe Interactions research group led by Nicolai V. Meyling at the The Department of Plant and Environmental Sciences, University of Copenhagen, Denmark.
Start date is 1 September 2025 or as soon as possible thereafter.

The project

The PhD project will form part of a collaborative research project entitled ‘Mechanisms and consequences of microbial induced resistance on trophic interactions and biocontrol efficacy’ funded by the Novo Nordisk Foundation.

Beneficial microorganisms can colonize the rhizosphere of plants and modulate plant defense mechanisms against insect pests. The project aims to quantify the short and longer-term effects of microbial induced resistance (MIR) on aphid populations feeding for multiple generations on sweet pepper plants inoculated with root-colonizing fungi. Aphid endosymbionts may have a context-dependent cost to their host, which may render them more responsive to MIR and affect resistance towards natural enemies, e.g., parasitoid wasps. A relevant broader conceptual framework is outlined by Martínez-Medina et al. (2024) TiPS: https://doi.org/10.1016/j.tplants.2024.05.010. The PhD project will investigate the interactive effect of MIR and aphid endosymbiont community on survival after parasitoid exposure. Further, the emission of volatile organic compounds of plants with/without MIR will be aligned with choice assays of an aphid parasitoid wasp to evaluate how MIR affects plant-insect communication at higher trophic levels. The project will bridge plant-microbe-insect interactions with chemical ecology in a trophic network approach, thereby contributing to our understanding of the full potential of beneficial microbes in plant production.

The PhD fellow will supervised by Nicolai V. Meyling in partnership with Dr Paul Becher at the Swedish University of Agricultural Sciences, Department of Plant Protection Biology, Alnarp, Sweden. The PhD fellow will during the appointment work together with a postdoc to be hired at the Swedish University of Agricultural Sciences, where parts of the project will be carried out. The Alnarp campus is located with 1.5 h travel from Copenhagen by public transport. The PhD fellow will spend approx. 6 months at Alnarp campus during the 3-year period.

Who are we looking for?

We are looking for a committed and enthusiastic graduate student to perform experimental work with plants, fungi and insects (aphids and parasitoids) and their interactions. In addition, the activities will include DNA/RNA extractions for genotyping e.g. organismal detection (fungi, endosymbionts) and gene expression studies. The project will quantify volatile organic compounds emitted from fungal inoculated plants and assess aphid microbial communities. The successful PhD student will thus obtain competences within ecological interactions, molecular techniques,  and analytical methods of chemical ecology and experimental manipulations of plants, insect, and fungi. We are looking for candidates with experience in any or several of the following areas: entomology, plant science, microbiology, chemical ecology, community ecology, DNA/RNA based molecular techniques. Most importantly, the successful candidate is curious and enthusiastic, must have a good grasp of handling experimental systems with several different organisms and an interest in learning new techniques.

Our group and research - and what do we offer?

The Insect-Microbe Interactions research group is a part of the Section for Organismal Biology, Department of Plant and Environmental Sciences, Faculty of SCIENCE, University of Copenhagen. We are located in Copenhagen. In the research group, we study a multitude of microorganisms interacting with insects, ranging from pathogenic to beneficial interactions. We study fundamental and applied aspects of these interactions to contribute to the sustainable development of plant protection, pollination services and insect production. Within plant-microbe-insect interactions, we study the ecological effects of fungi colonizing the rhizosphere and plant tissues as endophytes in different crop plants. Specifically, we wish to understand how and if the responses of the fungal inoculated plants can enhance the plant’s own defence against herbivores and assess how the fungi are compatible with other biological agents in a multi-trophic context. More information is available here: https://plen.ku.dk/english/research/organismal_biology/ipbc/
We offer a creative and stimulating working environment in a dynamic and international research group. Our research facilities include modern laboratories and various insect, plant, and microbiology rearing facilities, climate chambers as well as computational resources.
