Grenoble INP is a federation of 11 engineering schools and 24 research laboratories. Its research fields of interest are in Micro and Nano technologies, sciences of information and communication, materials, environment, energy and manufacturing systems. Grenoble INP has been developing partnership with industry for more than a century. It has created many spin-offs and has presently leading role in industrial clusters.

Research activities of CROMA cover large areas (materials, technologies, components, circuits and systems) which allow carrying out multidisciplinary research in common with our partners in nano-physics and -technologies, material chemistry, device engineering, circuit design or system manufacturing in electronics and optoelectronics.
Situated at convergence of many sciences and technologies, CROMA can play an important federating role to develop ambitious projects and to challenge the future of electronics.
