Researcher at the University of Valladolid, specialized in Privacy Engineering. I studied the Double Degree in Computer Science and Statistics (INDat), obtaining two degrees, one in Statistics and the other in Computer Engineering, both in 2023 by the University of Valladolid. I was awarded with the Extraordinary End of Degree Award in both degrees. I have presented research at Cybersecurity and Privacy conferences in Spain, such as JNIC 2024 and RECSI 2024, and I have been the recipient of competitive grants, including the Collaboration Grant to perform research tasks in university departments awarded by the Ministry of Education, Vocational Training and Sports in the 2022-2023 academic year, and the Banco Santander Grant for Master’s students in 2024. I have a B2 level of English.
Currently, I am a researcher in the Strategic Cybersecurity Project “App-PI (App Privacy Impact)”, funded by INCIBE with PRTR and NextGen EU funds, where I focus my work on Privacy and Security research in mobile applications. In addition, I collaborate in training and outreach activities in Cybersecurity and Privacy, giving workshops for users and developers in the framework of the App-PI project.
