Geomatics (GM)

Phd , Researcher

Anna Barra holds a PhD in Civil Engineering (geotechnics) from the Universitat Politècnica de Catalunya (UPC) University (Barcelona, Spain) (2022), a master’s degree in Engineering Geology (Geology Applied to Engineering, Land Use Planning and Risks) (2013), and a bachelor’s degree in Geological Sciences (2009) from Sapienza University of Rome (Italy). In 2011 she got the financial support from Sapienza University for a 4-months stay in Canada and a travel to Brazil in to carry on a collaboration with the University of Waterloo (Canada) and the Pontificia Universidade Católica (PUCrio, Rio de Janeiro, Brazil). In 2014 she has been working for one year at the Earth Science Department of Sapienza University on the project FRANARISK, a research agreement between the Earth Science Department of Sapienza University of Rome and the Province of Rome, to develop a landslide susceptibility study in an area of the Province of Rome (centre of Italy).

She arrived at CTTC in March 2015 as Visitor Researcher, holding a 9-months scholarship granted by University of Rome Sapienza, then she remained as Research Assistant (2016-2022), and she is now a Researcher (since 2022), in the Geomatics Research Unit (Remote Sensing Group).

She is contributing to the lines of satellite PSI/DInSAR, supporting all the related activities of data processing improvements and applications. She is supporting the coordination activities of several projects (i.e. Safety, U-Geohaz, MOMPA, etc). She is also contributing to the coordination and formation of new people (i.e., new entries in the group, PhD students, temporal internship). The main activities of Anna Barra can be summarized in: i. improvement of processing approaches for different aims and applications ii. development of post-processing methodologies and tools for an operational exploitation of DInSAR results in geological hazard monitoring and risk management iii. analysis and interpretation of remote sensing data iiii. Dissemination activities (i.e. websites, conferences, trainings).

Her expertise allows to face both sides of the DInSAR technique: the data processing aspects and the post-processing usage and interpretation (for applicative aims). She has a good knowledge about the following topics: i. the DInSAR techniques, ii. the processing software tools developed by the Geomatics division, iii. the final users’ needs and main requirements, iiii. the deformation phenomena related with both human activities and geological-geotechnical environment (land subsidence, slope instability, landslide, mining activities, consolidation).

Her main research focus is the use of DInSAR techniques for geohazard management, from wide-area application (wide area processing and big data management and analysis) up to a very local scale application (interpretation of specific phenomena and cross-validation).

She has participated in the proposal of several projects:
