Sonia Toubaline, PhD
Research Fellow
Dr. Sonia Toubaline worked with us as a research fellow on the SOGRID project, which aimed at testing in real conditions a G3-PLC (Power Liner Communication) architecture from electrical domestic meter to source station. Several technological innovations were designed, developed, deployed and assessed to insure a real-time control of low and medium voltage electrical networks.
Her expertise is in mathematical modeling and optimization.
Sonia is currently a faculty member at Université Paris-Dauphine. This is her new homepage.
