D. RESEARCH ACTIVITY
Philippe Roux is an experimentalist with a strong background in ultrasonics, underwater acoustics and geophysics.
During his PhD under the supervision of Mathias Fink (Paris, 1994-1997), he worked at the laboratory scale on time-reversal experiments in waveguides and sound-vorticity interaction. This earlier work led to the first Underwater Acoustic Coms’ experiment using time reversal in waveguides, which is, up to now, one of the main applications of time-reversal at sea.
He followed his PhD by a one-year post doc (1998) at the Scripps Institution of Oceanography (San Diego), where he learned about computational underwater acoustics in the team led by W.A. Kuperman. He participated to one sea cruise and started to work with ocean data.
He was hired as a full-time Research Associate at CNRS (Paris) in Dec. 1998. He mostly focused his research there on multiple scattering physics in reverberant cavities and time reversal (1999-2001). He also worked on the concept of acoustic resonator using the combination of the dispersion of elastic waves and time reversal in order to produce shock waves of very strong amplitudes from a small number of low-power transducers.
From 2002 to 2005, he was a visiting scientist and then a Research Associate at the Scripps Inst. of Oceanography (San Diego) where he built the ultrasonic laboratory and participated to several experimental campaigns at sea. His research turned toward the spatial-temporal coherence of ambient noise in underwater acoustics and geophysics. During that time, he also developed laboratory experiments in the MHz regime in order to complement the experimental results obtained at sea.
Since July 2005, he is back at ISTerre (Grenoble) where he funded his own acoustic laboratory through an ANR grant (2005). He maintained a strong collaboration with the Scripps Inst. of Oceanography where he spends one month per year. His research topics are centered on underwater acoustics and geophysics, the link between the two being his expertise in wave propagation in complex media and his dedication to multi-scale experiments both on the field and in the laboratory.
His work in geophysics deals with the use of seismic ambient noise recerded on arrays of sensors for the imaging and monitoring of the subsurface layers of the earth at scales ranging from tens of meters to thousands of kilometers. In underwater acoustics, his research is focused on the use of sensitivity kernels as a tool to invert for any kind of perturbation in a shallow water waveguide such as a local change of density (target detection and localization) or the monitoring of a thermal plume or even the imaging of a surface wave at the air-water interface. In most of his work, he takes advantage of a multi-channel electronics and an advanced laboratory set-up where he mimics the shallow water ocean propagation at the ultrasonic scale.
His publications ( 180 peer-reviewed papers, citation index 4800, h-index 34) range from wave scattering in ultrasonics to acoustic tomography in underwater acoustics or geophysics.
