I am a third year PhD student at the Large-Scale Data and Systems Group (LSDS) of the Imperial College London, under the supervision of Prof. Peter Pietzuch.

My research addresses the design and implementation of secure, high-performance, runtimes for the cloud. I am particularly interested in privacy-preserving systems and confidential computing. Most of my work is open-source and available on Github. During my PhD, I have interned with Intel Labs in the Datacenter security team.

I received a MSc in advanced mathematics, a BSc in mathematics, and a BSc in electrical engineering from the Technical University of Catalonia (UPC). In the past, I have worked as a researcher for the Barcelona Supercomputing Center (BSC), Nokia Bell Labs, the Swiss Center of Electronics and Microtechnology (CSEM), the University of Neuchatel, and the UPC.
