Between May 1st 2014 and December 31st 2018 I was a postdoc researcher at the Department of Astrophysics at the Radboud University in Nijmegen, being part of the LOFAR Cosmic-Ray Key-Science-Project. My research concerned the study of radio detection of high-energy cosmic rays (1016 - 1018 eV). In particular, the analysis I conducted concerned the study of the radio frequency spectrum and its relation to the mass composition of primary particles. The outcome of this analysis has been presented at several international conferences (e.g. ICRC2017, ARENA2018 ). The article containing the complete analysis and corresponding results is in its final stage. I have also been responsible of analysing data acquired during the LOFAR antenna calibration campaign using an external reference source. These calibration data have been a key point in understanding the systematic uncertainties in the frequency spectrum study. 

Moreover, I have been responsible of monitoring the LOFAR cosmic-ray data-taking, and the maintenance of the scintillator array installed in the innermost part of LOFAR which acts as trigger for the cosmic-ray data acquisition. In this task, I collaborated with the technicians of the Radboud University workshop whenever their intervention was required.

Besides those tasks, I was in charge of organizing the activities of the LOFAR group at Radboud University, among them to organize the weekly LOFAR cosmic-ray meetings, and to act as interface between the LOFAR Cosmic Rays Collaboration and the Netherlands Institute for Radio Astronomy (ASTRON) which is the organization managing the LOFAR array.
