Bastien Giraud received his Engineer’s degree in Computer Engineering, Electronics and Telecommunications from Institut Supérieur d’Electronique et du Numérique (ISEN, France) and his Master degree in Microelectronics at Polytechnique Marseille (France) in 2005. His major field concerns advanced circuit design. In 2005, he spent 5-months master thesis at Interuniversity MicroElectronics Center (IMEC, Belgium) where he studied 32KB SRAM matrix in Bulk-130n.

He received his PhD degree from Ecole Nationale Supérieure des Télécommunications (ENST, Paris, France) in December 2008. His PhD thesis was realized in the laboratories of Institut Supérieur d’Electronique de Paris (ISEP) in cooperation with CEA/Leti (France). This thesis is part of a French multi-laboratories project funded by the ANR (National Research Agency). The thesis is based on microelectronics design about SRAM memory in Double Gate SOI-FD sub-32nm technology, in which in-depth studies of SRAM memory cells and Sense Amplifiers (in Current and in Voltage) have been conducted.

Since January 2009, he holds a postdoctoral researcher position at UC Berkeley in the Berkeley Wireless Research Center (BWRC) laboratories under the supervision of Prof. Nikolic. His current research interests are in logic circuits and SRAM variability.
