I build deployable quantum-randomness infrastructure for cybersecurity, high-performance computing, and post-quantum systems — taking quantum physics from the lab to real-world products.

VP of Innovation and Lead Scientist at Quside Technologies. Co-inventor across 8 patent families (US, EP, CN, JP). PI of €5.6M+ in competitive R&D funding (Horizon Europe/EIC, CDTI). 30+ patent families under management.

At Quside I lead R&D strategy and technology transfer — from quantum random number generators to post-quantum cryptography stacks and entropy infrastructure at scale. I bridge the gap between our photonics hardware and the software and systems that make it deployable.

Ph.D. in Photonics (UPC/ICFO, 2018, Cum Laude; advisor: F. J. García de Abajo). MBA (Valar Institute, 2025). Physics at Universidad Complutense de Madrid. Currently pursuing a Law degree (UOC) at the intersection of technology, IP, and regulation.

I teach Software Architecture for Quantum Computers at UPC, supervise doctoral theses at UPC and ICFO, and build open educational tools like NanophotonicsLab and El Fotonario.
