Before returning to Universidad Carlos III de Madrid I was a postdoctoral researcher at Chalmers University of Technology, and then a Marie Skłodowska-Curie Global Fellow at MIT, where I co-organized the ICASSP 2024 Grand Challenge on data-driven interference rejection.

I am a member of the IEEE Information Theory Society, where I serve as Vice President of its Spain Chapter and sit on the Student and Outreach Committee. Through the committee I co-organize international data-science competitions, most recently at ESIT 2026 and ISIT 2026.

First Prize, IEEE ISIT Data-to-Information Challenge — 2025, with team ISAC Innovators
