Background

Ramon Hanssen is Antoni van Leeuwenhoek professor in Earth Observation. He studied aerospace engineering and geodetic engineering at Delft University of Technology (M.Sc. 1993). His graduation work focused on the use of the Radon transformation for the analysis of sparsely sampled data, with applications in satellite altimetry and imaging tomography.

In 1994, he worked as a researcher on potential field data inversion at the International Institute for Aerospace Surveys and Earth Sciences (ITC).

In 1995, he started his PhD research at the Delft Institute for Earth-Oriented Space research (DEOS) of Delft University of Technology on the geodetic analysis of repeat-pass spaceborne radar interferometry, with emphasis on error propagation. During this research, he worked as a visiting scholar at Stuttgart University (1996), at the German Aerospace Center (DLR, 1997) and at Stanford University (1997-1998) on a Fulbright research fellowship. In 2001 he received the PhD degree (cum laude) of TU Delft. At present, he is working in the field of radar remote sensing and geostatistics at the Faculty of Aerospace Engineering at TU Delft. His current research interests are the geodetic analysis of imaging remote sensing data, the influence of atmospheric delay on space-geodetic techniques, and the mathematical modeling and physical interpretation of deformation processes.

In 2001, he published a text book on Satellite Radar Interferometry, which is well recognized in the scientific community. He received a Fulbright Fellowship in 1997, the Innovational Research Award (Vernieuwingsimpuls) from the Netherlands Organisation for Scientific Research (NWO) and the Bomford Prize of the International Association of Geodesy in 2003. In 2007 he was a visiting scholar at the Nordic Volcanological Institute of the University of Iceland. In 2008 he was awarded the Antoni van Leeuwenhoek chair of Delft University of Technology.

In 2007 and 2008 he received the SBIR award from the Dutch Ministry of Economic Affairs for founded a TU Delft spin-off company for radar remote sensing and monitoring of water defense works, Hansje Brinker.

As of 2009 is leading the section of Mathematical Geodesy and Positioning, which focuses on GNSS algorithm development, navigation and applications, as well as imaging radar remote sensing.
