  • Modeling of broadband aeroacoustic sources using analytical models and acoustic analogies: application to trailing edge noise and turbulence inflow noise on wind turbine blades and marine propellers
  • Computational Aeroacoustic methods: direct noise simulations and hybrid methods based on incompressible flow simulations
  • Study of unstable regimes of wind turbine noise : amplitude modulation, dynamic stall noise
  • Acoustic propagation in the atmospheric boundary layer : modeling based on the parabolic equation and the time-domain solution of the linearized Euler equations
