Your Job:
The PhD project offered will be part of the Cluster of Excellence: PhenoRob - Robotics and Phenotyping for Sustainable Crop Production. PhenoRob performs world-leading research in robotics and phenotyping for sustainable crop production with the vision to transform crop production by optimizing breeding and farming management through developing and deploying new technologies. Within Phenorob, we develop novel agrogeophysical methods to obtain noninvasive subsoil information that can be used to advance root phenotyping and soil functions. Soil-root interactions will be analyzed across management scenarios using geophysics and numerical modeling. High-resolution subsoil characterization using electromagnetic induction (EMI), and ground penetrating radar (GPR) will be combined with soil sensors systems and UAVs at different scales. In particular, we will combine borehole and surface GPR as well as small-scale EMI measurements with root and shoot observations in controlled experiments (rhizotron facility) and field trials. In addition to field applications, novel inversion algorithms for ground-penetrating radar (GPR) and electromagnetic (EM) will be developed. These algorithms will enable high-resolution, quantitative time-lapse soil property measurements using high-performance, parallel computing. Together with our existing rich dataset, we will inform a soil-plant digital twin, enabling ML-based analysis of geophysical and rover approaches for field-scale root and soil characterization.
You will be part of a dynamic research team applying advanced geophysical methods to study soil–plant interactions. Your main responsibilities will include:
1. Developing and applying high-resolution time-lapse GPR and EMI imaging methods at multiple scales to enhance our understanding of the soil–root system
2. Designing and implementing novel inversion algorithms for GPR and EMI data
3. Identifying links between non-invasive agrogeophysical parameters and the soil–plant continuum
4. Improving small-scale process understanding of soil–plant interactions and transferring this knowledge to larger scales for applications in agricultural management
5. The project offers the unique opportunity to connect novel processing and inversion techniques to experimental data from different regions and link the findings to relevant processes of the soil-plant system.
