Portrait von Robert Koller

Dr. Robert Koller

Wissenschaftlicher Mitarbeiter

Current research 

·         Natural soils are heterogeneous and dynamic in terms of temperature, water and nutrient availability.

·         In the framework of the German phenotyping network (DPPN) I am aiming to link root morphological and functional traits in dynamic environments. This is critical in determining traits of resource efficient roots required in future crops.

·         Combining non-invasive Magnetic Resonance Imaging (MRI) and Position Emission Tomography (PET) enables monitoring and quantification of 3D root morphology and visualisation of carbon allocation to roots in response to temperature, water and nutrient availability.

Previous research

·         Soil fauna interact in complex belowground food webs.

·         In my previous work I was aiming to dissect multitrophic interactions of soil fauna and reveal the functional role of these interactions for carbon fluxes, nutrient mobilisation and plant performance.

·         In particular, I was focussing on how microfauna affect the functioning of plant symbionts for nutrient acquisition and carbon partitioning.
