PhD Position in Forest Microbiology: Soil Food Web Functional Capacity and Resilience under Climate Extremes Swedish University of Agricultural Sciences in Sweden

A PhD position is available at the Swedish University of Agricultural Sciences (SLU), Department of Forest Mycology and Plant Pathology, within the Forest Microbiology group. This department offers a vibrant, international research environment focused on plant-microbe interactions, mycology, and microbial ecology. The position is part of the WIFORCE Research School, a Wallenberg Initiative in Forest Research, which aims to address major challenges in forest biodiversity and climate change through innovative basic science and analytical tool development.

The research project investigates the functional capacity and resilience of soil food webs under climate extremes, with a particular focus on consequences for tree regeneration. Climate change is altering forest ecosystems, with increased temperatures, variable precipitation, and more frequent droughts and heatwaves threatening tree seedling survival. Seedlings rely on soil nutrient availability, microbial symbionts, and a stable soil food web for successful establishment, but the mechanisms by which soil communities support or constrain forest regeneration under both gradual and extreme climatic changes remain poorly understood. This project seeks to fill that knowledge gap, contributing to climate-smart, sustainable forestry strategies.

The successful candidate will conduct field experiments along climatic gradients in Sweden and controlled laboratory studies simulating drought and heatwaves. Research will assess how soil microbial and faunal communities (including protists and nematodes) respond to climatic variation, their resilience to stress, and how their functional capacity influences nutrient cycling and seedling growth. Training will be provided in field ecology, experimental design, and molecular techniques such as metabarcoding and functional gene assays. The position also offers opportunities to develop individual research directions in forest soil ecology.

Applicants should have a Master’s degree (or equivalent) in Ecology or a closely related field, with emphasis on plants, soils, or microbiology. Strong written and verbal English communication skills, critical and creative thinking, and the ability to conduct primary research in both field and laboratory settings are essential. Good numerical and statistical skills and previous experience in molecular biology are desirable. A valid driving license is required. SLU encourages applications from both Swedish and international candidates, especially those from under-represented groups.

The position is based in Uppsala, Sweden, and is offered as a four-year PhD student employment with salary and benefits according to university standards. The preferred starting date is 1 May 2026, or as agreed. Applications must be submitted in English through the SLU recruitment system by 10 February 2026, including a CV, degree project, degree certificates, transcripts, and contact details for two references. Non-Swedish citizens should also provide a copy of their passport’s information page. For more information about doctoral studies at SLU, visit the provided links.

SLU is committed to sustainable societal development and good living conditions on our planet, with a focus on the interaction between humans, animals, and ecosystems. The university values inclusivity and gender equality, welcoming applicants from diverse backgrounds and perspectives.
