General:

Prof. Georg Guggenberger holds a Professorial Chair in Professor and Director of the Institute of Soil Science in Leibniz University Hannover. He is focusing on soils, as they represent – together with water and agricultural/forestry products – the ultimate resource for human wellbeing. His research focus is on (1) nano to microscale analysis of structure and reactivity of soil components, (2) soil carbon and nitrogen cycling and its exchange with neighboring ecosystem compartments, (3) the response of permafrost soils on climate change, and (4) development of sustainable and innovative land-use management systems based on sound scientific evidence. This portfolio of research interests is connected to large experience in state-of-the-art spectroscopic and microspectroscopic techniques (e.g., as nuclear magnetic resonance spectroscopy, energy dispersive spectroscopy coupled to environmental scanning electron microscopy, high energy X-ray spectroscopic techniques, and X-ray photoelectron spectroscopy), biomarker methods, and stable isotope approaches at laboratory and field scale. At the applied side of his research his goals are to assess the consequences of land-use change and soil management on sustaining soil quality and to define from monitoring, process studies, and specific field experiments land-use systems that are ecologically sustainable and at the same time secure harvest and income on the long run.

Dr. Olga Shibistova is biogeochemist and plant ecophysiologist, and main area of her research has focused on the carbon cycling in terrestrial ecosystems at different scales. She got worldwide renowned by her studies on the carbon balance by estimation of CO2 exchange and portioning of carbon fluxes between atmosphere and terrestrial ecosystems. Besides, she is well experienced in research on permafrost soils in Siberian boreal and tundra areas with respect to composition, turnover, and stabilization and destabilization processes of organic matter. Her methodological repertoire is very rich and includes gas exchange measurements by closed and open chamber techniques, Eddy covariance applications, biomarker analysis in soil organic matter, and particularly the use of stable isotopes in unravelling processes and rates of carbon allocation in the atmosphere-plant-soil system.
