Senior Researcher and Lecturer

Hamburg University of Technology


I am a senior researcher and lecturer at the Institute of Software Security of Hamburg University of Technology (TUHH). 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.
