Biography

I defended my Ph.D. at FCUP in Computer Science with a research focus on data privacy and utility preservation of machine learning models. Currently, my work centers on privacy in AI: developing and evaluating methods that enable the responsible use of AI, uncovering how models can leak sensitive information, and designing defences that preserve their utility. Passionate about trustworthy AI, I’m committed to advancing technologies that safeguard individuals' sensitive information.
