    Jean-Marc Le Caillec is  a professor with the IMT Atlantique (Ecole Nationale Superieure des Télécommunications de Bretagne, Telecom Bretagne) in the 2IP (Information and Image Processing) department.  He obtained the degree of Engineer in Telecommunications in 1992 from Telecom Bretagne. He received the Ph.D. degree in Mathematics and Signal Processing of the University of Rennes I in 1992. From 1997 to 1999, he worked for Thomson AirSys (now Thales AirSys). He joined Telecom Bretagne as associate professor in 1999 and became full professor in 2007. From 2014 to 2020, he was in charge of the division CID (Knowledge, Information, Decision) of the Lab-STICC (Laboratory of sciences and technics for information, communication and knowledge, UMR 6285). research activities are in the framework of the "Science and Techniques for Engineers" and in particular in the signal processing domain. His activities are at the crossroad of several items: nonlinear systems, non Gaussian statistics, sea surface remote sensing and financial ,time series modelling. These four themes are complementary. In fact, the transfer function between the sea surface and the SAR (synthetic aperture radar) or HF radars is nonlinear due to the nonlinearity of fluid mechanism equations. Nonlinear system can be studied by using Higher Order Statistics (HOS) and underlying polynomial models of nonlinear systems. These methods have been applied to extract geophysical information from sea surface remote sensing data, either for civilian or military applications. Making decision for non Gaussian time series is also a frequent problem in financial time series, in particular in model calibration. More recently, He has initiated works on the defocusing problems of buried target images by a low frequency SAR since the Richard’s equation governing the soil moisture of the soil (and thus the dielectric constants) is also nonlinear. He has been an expert for the National Science Fundation (USA) and he represented France in  the former  NATO group SET-208 on the signal fusion for ground penetrating radars. He is member of the scientific committee of LATERAL (joint lab between Lab-Sticc and Thales LAS) and CORMORAN (joint lab between Lab-Sticc and Thales DMS). He is author and co author of more than forty papers and book chapters, half as first author.
