I obtained respectively my Master and PhD degree in 1993 and 1996 from the University of Montpellier (now University of Montpellier). From 1996 to 1997 I was in ATMEL company as IP core methodology R&D engineer. From 1997 to 200 I was assistant professor at the University of Montpellier 2, Polytech Montpellier (Microelectronic design) and LIRMM laboratory. Since 2004 I am full Professor and was at the head of the Microelectronic dpt of the LIRMM from 2007 to 2010. I am now deputy head of Polytech Montpellier (engineering school of Montpellier) in charge of research and industrial relationship. My research interests and skills concern system level architecture, with a specific focus in the security and cryptographic applications and Non-Volatile Computing based on MRAM. Since 2015 I am at the Head of the cluster of excellence Labex NUMEV (Digital and Hardware Solutions and Modeling for the Environment and Life Sciences), a structuring project (labeled in 2011 by the Programme d'Initiative d'Excellence) of the University of Montpellier. I am involved in different major conference as DATE, VLSI, FPL, ISVLSI, DAC and is (co)author of  more than 50 journal papers and 150 conference publications and 10 patents. I am also involved into the ALGODONE spin-off, company created with the support of the University of Montpellier, CNRS and SATT Axlr on IP Protection.
