Fabien is a pioneer in designing Network-on-Chip based multi-core and was the integrator of the first asynchronous-based Network-on-Chip published at ISSCC in 2007. He then took the lead of the second generation of Network-on-Chip based multicore dedicated to 3GPP-LTE applications published at ISSCC in 2010 and was the leader of the CEA team which has been working on the P2012 multi-core architecture in collaboration with STMicroelectronics and ST-Ericsson. At this period, his team elaborated one of the first 3D multi-core prototypes embedding a WIDE-IO DRAM memory called WIOMING.

Fabien is currently head of the digital architecture and design laboratory at CEA-LETI working on multi-core architectures and design with a focus on emerging technologies and new architectures using emerging technologies such as 3D TSV, 3D monolithic integration and emerging memories such as RRAM.
