Jose Antonio Garrido

ICREA Research Professor and Vice Director

Group Leader

Jose A. Garrido is an ICREA Research Professor and leader of the ICN2 Advanced Electronic Materials and Devices Group, which explores novel electronic materials, such as graphene and other 2D materials, and their potential in electronic and bioelectronic applications.

He received his Master’s and PhD degrees in Telecommunication Engineering from the Universidad Politécnica de Madrid in 1996 and 2000, respectively. From 2001 to 2004 he worked as a postdoc at the Walter Schottky Institute, Technische Universität München (Germany). He obtained his habilitation in experimental physics at this university in 2010 and from 2011 to 2015 held a lecturer (privatdozent) position at its department of physics.

In 2015 Jose A. Garrido joined the ICN2 where, in addition to his role as Group Leader, he is Vice-Director. He is the coordinator of the European project BrainCom, in which 10 institutions from 6 countries participate in the development of a brain implant that allows verbal communication in patients with aphasia. He is also the coordinator of the i-VISION project funded by La Caixa Foundation, where 5 institutions join forces in the development of a retinal implant to restore vision. In addition, he is also the leader of the GraphCAT project, which is part of a large initiative of the Catalan government aiming at supporting emerging communities with large innovation potential. The project involves over 20 institutions including industry and academia.

Jose A Garrido is also founder, Chief Scientific Officer, and member of Board of Directors of INBRAIN Neuroelectronics, an ICN2 spin-off that aims at the commercialization of graphene-based neural devices for medical applications. In March 2021, INBRAIN raised over 14M€ Series A led by Alta Life Sciences, Asabys Partners and CDTI to develop intelligent graphene-based neuroelectronic therapies for brain related disorders. In July 2021, INBRAIN signed a long-term partnership with the pharma Merck (Germany), creating a subsidiary (INNERVIA bioelectronics) to explore bioelectronic vagus nerve therapies for severe chronic diseases.
