Dr. Nieves Cubo Mateo (Madrid, 1991) is a biomedical engineer and internationally recognized pioneer in 3D bioprinting. She was the first to fabricate functional human skin using a low-cost bioprinter and living human cells, a milestone in regenerative medicine. She holds a PhD in Pharmacy from Complutense University and currently leads the ARIES research group at Nebrija University. At the age of 30, she founded her own research line and has since become Principal Investigator of national (AEI) and international (ESA) competitive research projects. She serves as Bioprinting Coordinator at UPAM3D, the clinical 3D printing unit at Hospital General Universitario Gregorio Marañón, where she contributes to the clinical translation of advanced class III implants and biomaterials. Dr. Cubo is an active science communicator and advocate for open science. She was selected by the MIT Media Lab as a Global Community Bio Fellow and is currently a Board Member of the Iberian Society for Biomaterials (SIBB) and National Young Investigator Representative for the European Society for Biomaterials (ESB). Her work bridges innovation, healthcare, and space exploration through her involvement in the ESA Topical Team on Bioprinting for Human Spaceflight. She has received awards such as the Julia Polak European Doctorate Award (ESB, 2021) and the Extraordinary PhD Award (UCM, 2022).
