Roberto Sabatini

Roberto Sabatini is a researcher at the Laboratory of Fluid Mechanics and Acoustics (LMFA, UMR 5509) in Lyon, France. His primary affiliation is with École Centrale Lyon (ECL) and the University of Lyon system. He specializes in acoustics research, focusing on aeroacoustics of rotating machines, compressible flow dynamics, and nonlinear acoustic phenomena. His work bridges fundamental fluid mechanics with applied research in environmental and geophysical acoustics.

Research interests include propagation of acoustic-gravity waves in the upper atmosphere, seismic infrasound analysis, and numerical modeling of wave interactions in complex environments. He contributes to projects involving volcanic eruption impacts, earthquake-generated acoustic signals, and multi-component gas dynamics in thermospheric regions. His work often employs advanced numerical methods like immersed interface techniques and spectral element approaches for wave simulation.

Recent studies focus on global atmospheric wave propagation, such as the Lamb wave induced by the Hunga Tonga eruption, and scalable models for ionospheric disturbances. He collaborates on interdisciplinary projects combining fluid dynamics with space physics, aiming to improve understanding of coupled atmospheric-ionospheric systems.

His technical contributions include advancements in underwater acoustics localization and efficient computational methods for elastic/acoustic wave scattering. Current research also explores nonlinear effects in infrasound propagation through turbulent fields and gravity wave breaking processes.
