Prof. Dr. Ralf Seppelt studied applied mathematics at the Technical University Clausthal Zellerfeld, Germany, obtained his doctorate degree at the Technical University Braunschweig, Germany, in agroecology, systems analysis and philosophy where he worked as research assistant and lecturer at Institute for Geoecology. After several research visits at the Gund Institute for Ecological Economics, Burlington and Maryland, USA, as well at the CSIRO in Canberra, Australia, he was appointed full professor for applied landscape ecology at Martin-Luther University Halle-Wittenberg, where he lectures courses on Environmental Modelling. He is head of the department for Computational Landscape Ecology. At UFZ he is responsible for the research topic Land use Options of the programme Terrestrial Environment of the Helmholtz-Association. In the BMBF programme on "Sustainable Land Management" he coordinates the synthesis project GLUES “Global Assessment of Land Use Dynamics on Greenhouse Gas Emissions and Ecosystem Services”. His major research focus is land resources management based on integrated simulation and modelling systems. He thus is interested in the interactions and interrelationship of anthropheric and biospheric processes. This requires methodological developments in landscape ecology such as model integration, hybrid model systems and scales in space and time.
