I am an Assistant Professor at Técnico (University of Lisbon), and a Senior Researcher INESC-ID Lisbon. Before, I was a Senior Researcher at Oracle Labs Zurich (working on GraalVM), and before that, 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.

• I am co-organizing MoreVMs’22

• I was invited to serve on the PC of OSDI’22

• Oracle Labs is opening new internship positions. Check their internship program.

• I am looking for PhD students! Feel free to contact me if you are interested in working on Systems and/or Programming Languages.
