Stefan Doerr is Professor of Wildland Fire Science in the Geography Department at Swansea University and leads the Department’s Environmental Dynamics Research Group. He studied Geography, Geology and Botany at Tübingen University (Germany), and his PhD (1998, University of Wales, UK) focused on the effects of fores fires on soils and hydrology in Portugal. He has held collaborative research positions at the CSIRO in Canberra and at Melbourne University (Australia), Universitat de València (Spain) and the US Geological Survey (Denver, USA), which focused on the relationships between fire severity, fire frequency, and geomorphological and hydrological responses of burned terrain. His current research, with field sites in all inhabited continents, also includes trends in fuels and fire, and fire impacts on water quality, ecology and social perceptions. He has published over 150 international journal publications with >8000 citations (Highly Cited Researcher in the cross-disciplinary sciences, Web of Science 2018) and is Editor-in-Chief for the International Journal of Wildland Fire.
