My research has three main components. In information security, I work on the protection of privacy. Specifically, I am interested in the preservation of personal information that is spread over the Internet and accessed by services such as search engines, social networks, geolocation websites, online learning and e-commerce.

I use cryptographic protocols and different techniques for privacy protection: k-anonymity, randomization, secure multiparty computation and privacy by design. I also work to improve privacy policies concerning the categorization and confidentiality of sensitive data.

In e-commerce, I am interested in customization (acquisition of customer profiles) and recommendation of products and services using algorithms such as demographic, content-based, collaborative and hybrid filtering.

In the context of intelligent tutoring systems, I am interested in learning strategies, human-computer interaction, assessment methods and learner modelling. To do this, I use artificial intelligence techniques including machine learning and data mining.

My research expertise is quantum cryptography. More precisely, I use quantum information to achieve advanced cryptographic tasks that would be impossible to do classically, or that can be based on weaker assumptions. I also enjoy research in post-quantum cryptography, the branch of classical cryptography that focuses on security against of a quantum adversary. I'm also interested in cryptographic solutions to privacy-friendly computing.
