Biography

I am a senior researcher and lecturer at the Institute of Software Security of Hamburg University of Technology. My main research focus stands at the intersection of human-computer interaction and privacy engineering. Particularly, I seek to create technological solutions for supporting the cybersecurity decisions of social network users and software developers. For this, I elaborate on digital nudging applications, their personalization by means of Artificial Intelligence (AI), and ethical issues arising from combining persuasion with AI.

Before joining the Hamburg University of Technology, I worked as a postdoctoral fellow at the University of Duisburg-Essen. From January 2020 to October 2021 I was the coordinator of the RTG “User-Centered Social Media” funded by the German Research Foundation (DFG). Between August 2018 and September 2021 I participated in the H2020 project “PDP4E: Methods and Tools for GDPR Compliance through Privacy and Data Protection Engineering”. In the past, I have worked as a software engineer in Denmark and as an undergraduate research assistant 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.

AssureMOSS: Assurance and certification in secure Multi-party Open Software and Services

H2020 European Project No. 952647
The Assurance and certification in secure Multi-party Open Software and Services (AssureMOSS) is to produce a coherent set of automated, lightweight techniques that allow software companies to assess, manage, and re-certify the security and privacy risks associated with the fast-paced development and continuous deployment of multi-party open software and services (for which we introduce the MOSS acronym). Ultimately, we aim at supporting the creation of more secure MOSS software.

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.

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.
