Join the European REAL-PETS project and contribute to cutting-edge research on privacy-enhancing technologies (PETs) and privacy-preserving digital identity solutions. Working with researchers and industry partners across Europe, you will help improve both the technical effectiveness and real-world usability of privacy technologies, empowering citizens with transparent and trustworthy privacy protections. REAL-PETS (link is external) will generate long-lasting technological, societal and industrial impact: strengthening EU technological sovereignty; enabling regulators to enforce privacy rules through empirical evidence; technology standardisation; fostering privacy-resilient products and services; and empowering citizens with usable, transparent and trustworthy privacy protections. As a Postdoctoral Researcher In The REAL-PETS Project, You Will Contribute To Two Key Research Tracks Within The Broader Project Objectives Usable Real-World Privacy-Enhancing Technologies Together with the other project partners, you will design and evaluate user studies that investigate user perceptions, usage practices and usability improvements of VPNs and other PETs. Attribute-based Identity Wallets Together with the other project partners, you will design and prototype a privacy-preserving age verification solution based on attribute-based credentials (ABCs). The goal is to enable users to prove age eligibility without revealing user identity, date of birth or other personal attributes. You will work under the supervision of Assistant Professor Christine Utz (link is external) for the usability part and under the supervision of Prof. Jaap-Henk Hoepman (link is external) for the attribute credential binding and age verification part. There will be no teaching or student supervision obligations. Does this sound like you? You hold a PhD degree in computer science, cybersecurity or a related field, or expect to obtain such a degree within a few months from now. You have solid programming skills and knowledge of the applied cryptographic technologies used in modern identity wallets (like Yivi (link is external) ). You have expertise in usable security and privacy (USP) and human factors research, with methodological expertise in designing and conducting empirical user studies, including controlled experiments, surveys, interviews and qualitative and quantitative data analysis. You have a strong interest in online privacy, data protection, identity management, the human factor in computing, and the ethical and societal implications of technology. You are curious about other perspectives and enjoy engaging with researchers from non-technical fields such as law, psychology or the social sciences. You are proficient in English (Dutch is not required) and have good communication, presentation and writing skills. If you do not meet all the above-mentioned requirements, please feel free to reach out to ask whether you should apply anyway.
