The SOMER Group works across tailing pedogenesis, degraded soil rehabilitation, organo-mineral interactions, and elemental biogeochemical processes through an integrated framework linking field experiments, controlled laboratory studies, and molecular- to nano-scale characterization. Our methodological strength relies on both in-house platforms and long-term collaborative access to large-scale facilities and analytical resources.
Synchrotron and Advanced Spectroscopy
- XAFS for resolving oxidation state, coordination environment, and mineral phase transformation of Fe, Al, Si, and related elements.
- Synchrotron FTIR mapping for identifying organic functional group distributions and their spatial coupling with mineral phases.
- STXM for micro- to nano-scale characterization of co-localization patterns between organic matter and minerals.
Nano- and Molecular-Scale Characterization
- NanoSIMS for micro-scale elemental mapping and organo-mineral interface analysis.
- 12T FTICR-MS for molecular-level characterization of complex organic matter mixtures.
Controlled and Field Experimental Platforms
- Indoor climate chambers for controlled studies of temperature, moisture, plants, and microbial processes.
- Large automated greenhouse facilities for larger-scale tailing rehabilitation and soil process simulations.
- Collaborations with ecological field stations for long-term monitoring and comparative field experiments.
