My interest in Earth Observation and the effect of climate change on Earth’s ecosystems developed during my B.Sc. and M.Sc. in Earth Sciences at the VU University Amsterdam, The Netherlands. This motivated me to pursue a PhD in remote sensing which I started in 2012 at the Department for Geodesy and Geoinformation, TU Wien with Prof. Wolfgang Wagner and as part of the Doctoral Programme on Water Resource Systems with Prof. Günter Blöschl. During my PhD I focused on assessing vegetation dynamics from spaceborne active microwave backscatter observations. Since obtaining my PhD in 2016 I have been working as a researcher at TU Wien in the field of microwave remote sensing.

My area of expertise is the development of retrieval algorithms for vegetation and soil moisture from active microwave observations, in particular from the Advanced SCATterometer on-board of EUMETSAT Metop satellites and from the Synthetic Aperture Radars on-board of the Copernicus Sentinel-1 satellites. In addition, I work on the validation of Earth Observation datasets with in situ data collected from networks and field campaigns.

Currently I work on my ESA Living Planet Fellowship project SHRED: Sentinel-1 for High REsolution monitoring of vegetation Dynamics. The objective of SHRED is to develop and use a novel high-resolution vegetation optical depth dataset based on ESA’s Sentinel-1 satellites to improve our understanding on the local impacts of water availability on vegetation at a global scale using novel machine learning approaches.
