The School of Geography, Earth and Environmental Sciences and the Birmingham Institute of Forest Research wishes to recruit Doctoral Research Fellow (PhD studentship) to support the work of Professor Sami Ullah. This European Council funded PhD studentship is available from 01/01/2026 for three years. The successful applicant will be responsible for undertaking research on assessing trade-offs of soil organic carbon for biomass carbon gain in temperate forests under elevated atmospheric CO2 enrichment as part the FutureForests Doctoral Network, an EU-funded Marie Skłodowska-Curie’s Actions (MSCA) initiative.
FutureForests aims to train 15 next generation scientists in assessing the impacts of global change on European forests, utilising a unique network of European flagship field forest facilities covering the dominant forest types and regions (dry Mediterranean, temperate and boreal) in Europe. FutureForests connects nine manipulation facilities for addressing emerging research questions and engages >20 academic and associated partners (NGOs, Industry & Government organizations) for delivering an interdisciplinary, integrated and transferable career skills programme.
Individual projects within the FutureForests programme map into four key interrelated science objectives with a focus on assessing responses of (1) tree functional processes including leaf metabolism, growth, C and water relations, (2) soil processes including nutrient cycling and soil organic matter dynamics, (3) impacts of global change on biodiversity and tree vulnerability to pest and diseases, and (4) advancing modelling of forest responses to climate extremes and fire risk reduction. FutureForests combines excellent trainings for doctoral researchers, diverse supervisions and international mobility for impactful research to benefit society and the economy and to inform forest policies under the EU Green Deal and international climate mitigation efforts (Paris Climate Agreement, 2015). FutureForests is to provide next generation scientists with skills and knowledge “most wanted” in academic and non-academic employability sectors.
This specific Doctoral Research Fellow position at the Birmingham Institute of Forest Research (BIFoR) and School of Geography, Earth and Environmental Sciences at the University of Birmingham, UK focuses on assessing trade-offs of soil organic carbon for biomass carbon gain in temperate forests under elevated atmospheric CO2 enrichment. Over the last 9 years of CO2 enrichment at BIFoR’s Free Air CO2 Enrichment (BIFoR-FACE), mineralization of soil organic matter (SOM) increased significantly to meet enhanced tree nitrogen demands. The faster nitrogen supply in soils is driven by enhanced root exudation into the rhizosphere together with increased fine root biomass and mycorrhizal turnover for nutrient acquisition. This raises a question if enhanced N acquisition via SOM mineralization may trade stable soil carbon for biomass carbon gains.
Key objectives of this studentship are: (1) Assess changes in the quantity and quality of SOM in soils collected over 11 years (fresh and archived soils) using fractionations and NMR spectroscopy and (2) investigate soil enzyme functions and N mineralization in fresh soils following 10 years of eCO2 enrichment. Complementary analysis of SOM quantity and enzyme functions at selected manipulation facilities in Italy (University of Bologna), Germany (Technical University of Munich) and Switzerland (WSL Research Centre) will be undertaken to compare eCO2, recurrent droughts and vapour pressure deficits impacts on SOM stocks and resilience under global change.
To support, coordinate and lead research activity under the direction of the principal investigator(s) as appropriate to the FutureForests project.
