Philip Poole

Philip Poole is a Professor of Plant Microbiology at the University of Oxford's Department of Plant Sciences and Senior Research Fellow at Somerville College. His research focuses on plant-microbe interactions, nitrogen fixation, and rhizosphere microbiology. He has led major international projects including the BBSRC-NSF Synthetic Symbioses program (2014-2019) and the India-UK Nitrogen Fixation Consortium (2016-2019). With 26 grants as PI from the UK's BBSRC, he has secured over £10.5 million in funding.

His work includes pioneering bacterial Lux biosensors for metabolite analysis, transcriptomics under sterile conditions, and metatranscriptomics in soil to study microbiome-plant interactions. Current projects model nitrogen fixation biochemistry in legume nodules and investigate rhizobia lifecycle transitions from rhizosphere colonization to symbiotic bacteroid differentiation.

He co-directs the Oxford Centre for Plants for the 21st Century and serves on editorial/advisory boards for Microbiology UK, The Journal of Bacteriology, and Pivot Bio. His contributions include elucidating the ammonia-alanine pathway for nitrogen secretion and demonstrating symbiotic auxotrophy dependencies in bacteroids.

Key achievements include developing global mutagenesis strategies (INSeq) and advancing understanding of microbial community structures in the rhizosphere. His research integrates molecular, genetic, and systems biology approaches to address global challenges in sustainable agriculture.
