Dr. Ralf Metzner serves as Deputy Head of Enabling Technologies and Team Leader of Plant Radiotracers at the Institute of Bio- and Geosciences (IBG-2: Plant Sciences), Jülich Research Centre. His leadership focuses on developing non-invasive imaging methodologies to study plant transport processes, with direct applications in sustainable agriculture and bioeconomy initiatives.
Metzner's research centers on plant transport physiology, particularly the demand-driven allocation of photoassimilates between photosynthetic and non-photosynthetic organs. He pioneers the use of short-lived radiotracers (primarily carbon-11) coupled with Positron Emission Tomography (PET) and Magnetic Resonance Imaging (MRI) to visualize three-dimensional carbon dynamics in living plants. This approach overcomes traditional limitations in studying phloem transport, enabling real-time observation of carbon flow under various environmental stresses including drought and disease.
Analysis of his recent publications (2022-2025) reveals three dominant research trajectories: development of the phenoPET plant-dedicated scanner system, investigation of carbon allocation patterns in response to biotic/abiotic stresses, and exploration of plant-microbe interactions in the rhizosphere. His work consistently bridges plant physiology, imaging technology, and agricultural science to address climate adaptation challenges.
Metzner leads the Plant Radiotracers team that operates specialized imaging infrastructure including the phenoPET scanner and integrated MRI-PET systems. This facility enables non-invasive 3D analysis of root systems in soil environments, supporting Jülich Research Centre's mission to develop sustainable plant production solutions through advanced phenotyping technologies.
