===============================================================
Research Director at [ONERA](http://www.onera.fr) DEMR Department (Advanced Methods for Signal Processing Unit)
**Short Bio:** Ph.D. student from 1988 to 1991 in the Radar System Division at ONERA (the French Aerospace Lab), I joined ONERA as a scientific researcher in January 1992 and defended my Ph.D. Thesis in April 1992. During the reorganization of ONERA in September 1997, I joined the Advanced Methods for Signal Processing unit of the Radar and Electromagnetism Department in the Physics Domain. In September 2002, I became the ALBATROS Project leader, which led to the development, control, and emphasis of new techniques and research made for the ONERA DEMR RAMSES airborne system (SAR image algorithms, interferometry, polarimetry, thesis supervisions, software development, etc.). In August 2003, I became a member of the Scientific Committee of the ONERA Physics Branch. I was elected President of the DEMR Scientific Advisory Board in January 2006 and again in January 2007. In January 2008, I joined the French-Singaporean SONDRA Lab on a part-time basis (two days per week) to supervise Signal Processing activities. I was an attached scientist in January 2010 for one year at DSO National Laboratories in Singapore. In 2011, I obtained a Research Directorship Habilitation (HDR) thesis in Signal Processing from the University of Paris-Sud and my qualification to the University Professor position. In 2015, I became a member of the Special Area Team (SAT) in Theoretical and Methodological Trends in Signal Processing (TMTSP), EURASIP. My research interests are centered on the topic of Statistical Signal Processing for radar and SAR applications such as Time-Frequency, imaging, robust detection, and parameters estimation.
