Biography

I am a postdoctoral fellow at the University of Duisburg-Essen working on areas of privacy and cybersecurity. My main research focus is human-computer interaction with special attention to privacy decision-making processes in social network sites. Particularly, I am interested in digital nudging applications to cybersecurity, their personalization through Artificial Intelligence (AI), and ethical issues arising from combining persuasion together with AI. Since, August 2018, I am a member of the H2020 project “PDP4E: Methods and Tools for GDPR Compliance through Privacy and Data Protection Engineering” and since January 2020 the coordinator of the RTG “User-Centered Social Media”.

Before joining the University of Duisburg-Essen, I worked as a software engineer in Copenhagen, Denmark; and as a student fellow at the “Universidad Tecnológica Nacional” (UTN-FRSF) in Argentina. Besides conducting my research, I am involved in multi-stakeholder forums for the discussion of public policies and Internet governance issues. Particularly, in debates concerning the users' right to privacy and control over their private information.

PDP4E: Privacy and Data Protection for Engineering

H2020 European Project No. 787034
PDP4E is an innovation action that aim at providing software and system engineers with methods and software tools to systematically apply data protection principles in the projects they carry out, so that the products they create comply with the General Data Protection Regulation (GDPR), thus bringing the principles of Privacy and Data Protection by Design to practice. PDP4E aims to widespread the creation of products, systems and services that better protect the privacy and personal data of EU citizens.

PDP4E: Privacy and Data Protection for Engineering

User-Centred Social Media

DFG Graduiertenkolleg No. 2167
The research training group (RTG) UCSM provides an interdisciplinary research environment with computer science and psychology as the main contributing disciplines. From this interdisciplinary perspective, it addresses research challenges related to Social Media which are understood as complex socio-technical systems characterized by features such as user-generated content, social interaction and awareness, and emergent functionality. Significant research gaps have been identified with respect to analyzing and understanding the characteristics and determinants of user behaviour, both at the individual and the collective level, as well as regarding the user-centred design of social media systems.

Roles: Coordinator (01.2020 - onwards), Ph.D Candidate (11.2015 - 02.2019)
