I graduated first from University Institute of Technology in 1984 as a Technician and followed an afterwork long training class that allowed me to graduate from CNAM (Conservatoire National des Arts et Metiers) and get my engineer degree in 1993. My first professional experience was dedicated to optical fiber audiovisual transmission systems in Thomson-CSF Rennes. Then I joined Thomson Consumer Electronics on 1996 and designed different wireless transmission frontends for HIPERLAN2/802.11 standards and also a video sender operating in the 5.8 GHz ISM band. From 2001 to 2003 I moved as an expatriate to Princeton area where Thomson Inc. opened a new research laboratory. I worked on a 3G cellular network project and more particularly on the design of a WCDMA frontend terminal. Back to Rennes I managed different wireless communication projects especially in the Digital Terrestrial TV domain. From this long wireless domain experience I decided to acquire a new expertise in the digital domain on 2009. As a researcher I developed software tool to repair video streaming packet lost through internet path. I touched also android environment thanks to a project dealing with activity sensing based on sensor data capture. That was my starting point to the IOT sensing domain and Machine Learning(ML) field for which I developed new skills especially in the acoustic space. Since 2014 I covered different aspects of acoustic ranging from supervised domestic sound recognition to unsupervised speaker voice identification based on hierarchical clustering algorithms.
