bzl.

Bio

I am a researcher at Microsoft Research Cambridge, working on confidential computing. Prior to joining MSR in November 2018, I was a tenured faculty at the IMDEA Software Institute, a postdoc at the Max Planck Institute for Software Systems, and a Ph.D. student at ETH Zurich. I studied mathematics and computer science at the Universidad de Chile, the Universidade Federal de Campinas, and the University of Konstanz, from which I received a M.Sc.

Research Interests

My research focuses on the foundations of computer security. In particular, I am interested in quantitative notions of security, and in techniques for computing corresponding guarantees for real systems. I apply my research to the analysis of side-channel attacks (and countermeasures) and to privacy-preserving data publishing.
