Introduction
I focus on both technical and human-computer interaction (HCI) aspects of privacy & security. I recently particularly focused on the privacy issues that arise when using wearable activity trackers (WAT). I also have a particular interest in computer ethics and the impact of new technologies on society, especially related to AI and IoT.

With the increased performance of large language models (LLMs), conversational agents (CA), such as ChatGPT, are nowadays available to any individual requiring little technical knowledge and skills. Initial studies that have investigated related privacy risks primarily focused on either technical aspects and misuse of these tools, or captured overa...
Health-related data (HRD) about individuals are increasingly generated and processed. The sources and volume of such data have grown larger over the past years, they include wearable devices, health-related mobile apps, and electronic health records. HRD are sensitive, have important privacy implications, hence hold a special status under existing...
Wearable activity trackers (WATs) have recently gained worldwide popularity, with over a billion devices collecting a range of personal data. To receive additional services, users commonly share this data with third-party applications (TPAs). However, this practice poses potential privacy risks. Privacy-enhancing technologies have been developed to...

Over the past decade, wearable activity trackers (WATs) have become increasingly popular. However, despite many research studies in different fields (such as psychology, health, and design), few have sought to jointly examine the critical aspects of utility (i.e., benefits brought by these devices), privacy, and security (i.e., risks and vulnerabil...
Wearable trackers are believed to enhance users' self-knowledge, but their impact on the relationship that people have with their own bodies is relatively unexplored. This study aims to shed light on the potential of physiological data collected by a commercial wearable activity tracker to influence how users relate with their own bodies, specifica...
Wearable devices, such as wearable activity trackers (WATs),are increasing in popularity. Although they can help to im-prove one’s quality of life, they also raise serious privacyissues. One particularly sensitive type of information has re-cently attracted substantial attention, namely personality, asit provides a means to influence individuals (e...
The number of users of wearable activity trackers (WATs) has rapidly increased over the last decade. Although these devices enable their users to monitor their activities and health, they also raise new security and privacy concerns, given the sensitive data(e.g., steps, heart rate) they collect and the information that can be inferred from this da...
Fitness trackers are increasingly popular. The data they collect provides substantial benefits to their users, but it also creates privacy risks. In this work, we investigate how fitness-tracker users perceive the utility of the features they provide and the associated privacy-inference risks. We conduct a longitudinal study composed of a four-mont...
