PhD Position

Agricultural sciences; Biological sciences » Biology Researcher Profile: First Stage Researcher (R1) Positions: PhD Positions Application Deadline: 30 Nov 2026 - 23:59 (Europe/Madrid) Country: Spain Type of Contract: Temporary Job Status: Full-time Hours Per Week: 37,5 Offer Starting Date: 1 Jan 2027 Is the job funded through the EU Research Framework Programme?: Not funded by a EU programme Is the Job related to staff position within a Research Infrastructure?: No Posted 2026-11-10 Offer Description The successful candidate will carry out a PhD within the framework of the RHIZOINTERACT project (PID2025-169677OA-I00), focused on bacterial interactions and the ecological principles governing the assembly of the wheat rhizosphere microbiome and the integration of plant-beneficial inoculants. A major component of the project will involve bioinformatics and metabolic modelling. The researcher will reconstruct, analyse and curate genome-scale metabolic models (GEMs), perform flux balance analysis (FBA), and model metabolic interactions among bacterial strains and microbial communities. The candidate will also analyse bacterial genomes and high-throughput sequencing datasets, including functional annotation, comparative genomics, amplicon sequencing, metagenomics, metatranscriptomics and related multi-omics data. Experimental work will complement these computational approaches and will include the maintenance and phenotypic characterization of plant-associated bacterial collections, classical and molecular microbiology, bacterial genetics, and bacteriophage propagation and characterization. The project will involve the design and execution of bacteria–bacteria interaction assays, including metabolic and non-metabolic interactions, co-cultures, synthetic microbial communities (SynComs), arrival-order experiments, strain drop-out/drop-in experiments, and assays of inoculant integration. Computational predictions will be iteratively tested and refined using experimental data. The researcher will also perform plant–microbe experiments using wheat microcosms and monitor bacterial community composition and dynamics. The candidate will analyse, integrate, interpret and present the resulting data, participate in national and international scientific meetings, contribute to scientific publications, outreach and knowledge-transfer activities, and may participate in the co-supervision of BSc and MSc research projects.
