Filippo Grassia received the master degree in computer science engineering (obtained with honors, 110/110 cum laude) at the University of Catania (Italy) in 2006. He had several working experiences as computer science researcher starting with the Thales group in Netherlands and then joining (2007-2009) the INFN (National Institute of Nuclear Physics - Department of Physics - University of Catania, Italy) is having also the opportunity to get a master in materials science (2009).
In January 2010, He started an interdisciplinary research at the interface between engineering, materials and biology. He was awarded a Marie-Curie Ph.D. research fellowship in the European FACETS-ITN project and He did his Ph.D. (2010-2012) in the bio-electronics group at the IMS (Integration from Materials to System UMR 5218 CNRS) Laboratory, Bordeaux, France. He received from the University of Bordeaux 1, the Ph.D. degree in electronic engineering on January 7th 2013, obtained with the mention 'très honourable'.
Since January 2013 He is involved in the European Brain-Bow project as CNRS post-doctoral fellow (2013-2014) in the IMS Laboratory, working on experimental and theoretical studies to design neuromorphic chip for brain repair that will reproduce the functional organization of a damaged part of the central nervous system.
From January 2013 up to now: CNRS post-doctoral fellow (Brain-Bow project), IPB - IMS laboratory UMR 5218 CNRS, Bordeaux (France).
From January 2010 to December 2012: Marie Curie Ph.D fellowship (FACETS – ITN project), IPB - IMS laboratory UMR 5218 CNRS, Bordeaux (France).
