About me:
I am a Principal Research Scientist at Telefonica Research, an Associate Professor at Universitat Pompeu Fabra in Barcelona, and I serve as an IEEE Distinguished Lecturer. I was previously with Nokia Bell Labs and hold a dozen patents on wireless technologies. I authored two IEEE ComSoc Best Readings, including a book, and received Best Paper Awards at IEEE PIMRC (2019) and IEEE Globecom (2022). I received the IEEE Communications Theory Technical Committee Early Achievement Award (2023), the IEEE ComSoc EMEA Outstanding Young Researcher Award (2018), and my research was featured three times on “La Vanguardia”, the leading newspaper in Catalonia, Spain.
