I am currently an Assistant Professor at SONDRA, the French-Singaporean laboratory of CentraleSupelec. My research interests include robust estimation, performance bounds and resolution limits applied to statistical signal processing and for Radar applications. Recently, I am also interested in machine and deep learning approaches for Radar applications.
