I am a researcher in Bell Labs department for Distributed Reality Solutions, specializing in real-time and high-scale video processing and distribution systems, as well as Quality of Experience.
I have deep experience in real-time and high-scale video processing and distribution systems. Before joining Bell Labs, I was an R&D systems designer in Nokia Video BU, where I was a core designer of video products for IPTV and OTT systems, including error protection, fast channel change, DRM, content personalization and video transcoding. In parallel, I was also a key member in several research projects around video Quality of Experience, immersive 3D communications and personalized content. This allowed me to get a PhD in Telecommunication Engineering (Universidad Politécnica de Madrid, 2013), which received Ericsson Spain award to the best PhD Thesis in applications for multimedia environments.
I am currently researching how to use technology in general, and immersive media in particular, to improve human communication. I am particularly interested in how to measure the Quality of Experience of immersive communications, and this is why I am co-chair of Immersive Media Group at the Video Quality Experts Group (VQEG).
