Short Bio & Research

I am currenty a Senior Researcher at Oracle Labs Zurich, working on GraalVM. Before joining Oracle Labs, I was a Post-doc Researcher in the Systems Group, ETH Zurich, which I joined after receiving my PhD in CS from Técnico (University of Lisbon).

Most of my research focuses in the intersection between systems and programming languages. I am especially interested in optimizing language runtimes for cloud environments such as Microservices and Serverless. Besides language runtimes, I work on Operating Systems, and Parallel and Distributed Systems.

Contact me if you are interested in doing research in areas related to runtime languages or cloud environments. There are often open research positions in ETH Zurich (Systems Group), University of Lisbon (INESC-ID Lisbon), and University of Oslo.
