Biography

Stefan Schlaffer received the Diplom in Geoecology from University of Bayreuth (Germany) in 2007 and the Dr. rer. nat. (PhD) in Remote Sensing from TU Wien (Austria) in 2017. From 2008 to 2010, he worked as a hydrological modeller at Dr.-Ing. Karl Ludwig Wasserwirtschaft-Wasserbau GmbH in Karlsruhe (Germany) on flood forecasting.

Between 2010 and 2015, he was a research assistant at the GEO department of TU Wien working on automatic delineation of flooded areas from SAR data. In 2015, he received a Marietta Blau scholarship to carry out a research stay in the framework of his PhD at Luxembourg Institute of Science and Technology (LIST). From 2017 to 2018, he was an integrated expert on capacity building in GIS and remote sensing at the Acopian Center for the Environment of the American University of Armenia (AUA) in collaboration with the Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ). From 2018 to 2019, he worked as a Research Assistant at the German Aerospace Center (DLR) in Oberpfaffenhofen (Germany) on operational flood mapping from SAR sensors, such as Sentinel-1 and TerraSAR-X.

Since December 2019, he is with the CLIMERS group at TU Wien. His research interests include the retrieval of hydrological variables such as surface water dynamics and soil moisture from earth observation data and their application in hydrology and vegetation studies.
