head of the NewSpace SAR Research Group. Since 2019, he
has also been a lecturer with Ulm University, Ulm, Germany.
In 2017, he was a visiting research scientist with the NASA
Jet Propulsion Laboratory, Pasadena, California, where he
analyzed novel acquisition modes for the NASA Indian Space
Research Organization synthetic aperture radar (SAR) instrument.
He has authored or coauthored more than 80 research
articles in peer-reviewed journals and international conference
proceedings, and he holds eight patents in the field of
SAR. His research interests include the conception of innovative
SAR modes for high-resolution wide-swath imaging
and the development of low-cost SAR solutions for frequent
and enhanced Earth monitoring. He has been a member of
the Technical Program Committee of the European Conference
on SAR (EUSAR) since 2016. He was a recipient of the
First Place Student Paper Award at EUSAR in 2014, the IEEE
Geoscience and Remote Sensing Society Letters Prize Paper
Award in 2015 and 2017, and the ITG Dissertation Award in
2017. He is cochair of the Working Group on Remote Sensing
Instrument and Technologies for Small Satellites of the
IEEE Geoscience and Remote Sensing Society's Technical
Committee on Instrumentation and Future Technologies. He
is currently an associate editor for IEEE Geoscience and Remote
Sensing Letters. He is a Senior Member of IEEE.
