I like to do research in the sweet spot between programming languages and systems. I am an active contributor in the Graal.js project, and I am involved in other projects based on GraalVM. My research interests include managed language runtimes (aka Language VMs), dynamic program analysis, runtime optimization and performance, parallelism, and broadly speaking Data processing systems and Cloud computing. I am especially interested in all possible interactions between language VMs and other systems (such as RDBMSs, datalflow systems, FaaS frameworks, etc.), and I enjoy to build real stuff.

I am organizing VMIL at SPLASH2019. I am a regular reviewer for journals (e.g., ACM TACO, the VLDBJ), and conferences/workshops (e.g., Middleware, Meta, Reflect, ICWE, SC, etc.)
