As of 2022, I am an Assistant Professor at the Cheriton School of Computer Science at the University of Waterloo, and a member of the CrySP group. In March 2024, I became the Interim Associate Director of the Waterloo Cybersecurity and Privacy Institute (CPI), and am officially serving as Associate Director for the Institute since January 2025. My track record counts with over 30 peer-reviewed publications, several of which included in top venues for computer and communications security (IEEE S&P, ACM CCS, USENIX Security, NDSS), as well as other venues such as PETS, the world's premier forum dedicated to computer privacy. I am honored to have received a 2025 FOCI Rising Star Award for my continued work in the field of internet freedom.
Previously, I completed my PhD on Information Systems and Computer Engineering at Instituto Superior Técnico (IST) - Universidade de Lisboa, under the kind supervision of Prof. Luís Rodrigues and Prof. Nuno Santos. During this time, I conducted my research at the Distributed Systems Group at INESC-ID Lisboa but also had the chance to undertake a research internship at Carnegie Mellon University under the supervision of Prof. Nicolas Christin. In late 2021, I was fortunate enough to become a post-doc at Rice University under the supervision of Prof. Ang Chen.
My Curriculum Vitae can be found in this link.
Research interests: My research is focused in network security and privacy, with particular emphasis on statistical traffic analysis and Internet censorship circumvention. I take additional interest in digital forensics.
