Core business
Alain Loussert is the head of the Marseille engineering school campus and a researcher in the field of underwater acoustics. He is also trained in telecommunications. He implements finite element modeling methods in his work on sensors for marine applications. Alain is one of the specialists of ATILA, a simulation software for transducer modeling, developed at ISEN Lille in partnership with the French Navy. Alain also uses his expertise in agriculture by proposing bolus-sensors ingested by cattle to carry out monitoring operations (heart rate, temperature measurement) that provide information on the animal's state of health.
Prospective
Profitability is a prerequisite for the large-scale implementation of new technology, including in the healthcare field. Robots could be used to provide personal assistance, but questions remain as to their reliability, safety, well-being and human comfort. We might wonder what would happen if every human were equipped with a chip giving him instant access to all human information. Would it be better or worse? That's an open question. In any case, we're heading for ever-greater miniaturization, connectivity and data exchange. What remains to be decided, on a case-by-case basis, is the relevance and purpose of the devices that could be designed and made available.
360°
Autonomous sensors are synonymous with electronics and energy, thanks to embedded systems and the IoT. These are just some of the teams of experts with whom Alain Loussert collaborates. In the field of digital health, he is in particular in contact with the CHU and the University of Nîmes, who contribute their know-how in chemical attack and pollutant detection. Numerous collaborations are also in place with local companies or as part of the Yncréa group's "Health and Big Data" research chair. Research work - notably on the design of optically-based intelligent sensors - is bringing the "ethics" component to the forefront of ISEN's concerns.
About me
I completed my thesis under the supervision of Professor Jacques DELUSTRAC at the Université de Toulon et du Var (UTV), with a research grant from the DGA from February 1991 to June 1994. My thesis focused on the optimization of new reflector antenna concepts for very low-frequency transmissions in water. By construction and physical effects, an antenna becomes omnidirectional as soon as its dimensions become small compared with the wavelength of the transmitted signal. In fact, as soon as you "go down" in frequency, the size and mass of an antenna, especially if reflectors are added, quickly become a nuisance. What's more, experiments require larger budgets. In this case, modeling is the only way to optimize reflectors so as to make such an antenna directive. During the first year of my thesis, I had the opportunity to turn my hand to teaching, and this experience was equally rewarding. I then began my career in industry, where I went on to design sonars and transducers for several companies working directly with the DGA or the French Navy. After working for several years in industry, I decided to give a new direction to my career and turn to both teaching and research by applying to a leading engineering school specializing in electronics and computer science (ISEN). Here, I was able to pass on knowledge and working methods to students, as well as continuing my work in my field of expertise. I took charge of a research laboratory in 2001 (Instrumentation and Acoustics Laboratory), managing a team that grew to six people. To date, this has enabled me to supervise four PhD students and a number of Master's trainees. My research activities have continued in the field of underwater acoustics, from signal processing for data compression, through MIMO acoustic communications, to the development of new modeling and characterization procedures for single crystals, while maintaining my expertise through numerous conferences, articles, industrial contracts and supervision of European contracts (expert evaluator for the EEC). The "habilitation à diriger les recherches" that I passed in 2014 was motivated by the desire to continue my activities as a teacher-researcher while becoming more involved in the supervision of one or more research teams.
