Research interests and activities

Underwater acoustics, underwater acoustic communication and geoacoustics with emphasis on modeling of sound propagation, signal processing and geoacoustic inversion

The current research activities include

• modeling of wave propagation in acoustic, elastic and pore elastic media with applications in underwater, environmental noise, underwater object/target detection; 
• characterization of underwater channel for acoustic communication and environmental monitoring;
• signal processing and geoacoustic inversion for seabed characterization.
