Biography:

My main areas of expertise are underwater acoustics, signal processing, and geostatistical data analysis and modelling.

I develop methodologies and software for processing large amounts of acoustic data coming from a range of sensors (Multibeam echosounders, Split beam, sub-bottom profiler...). I spend important amount of time at sea supervising the data acquisition (trawl and acoustics fisheries surveys as well as geological survey), leading biological sampling, as well as testing and designing new systems.
