Research Areas

Our group(Wave Physics Group)is interested in the analytical study of a series of physical problems involving waves. Our present research includes problems in classical acoustics, e.g. acoustic metamaterials, and problems in aeroacoustics in the aviation and energy sectors, e.g. jet noise and trailing-edge noise.

Join us

Candidates with a strong analytical background in physics, acoustics, fluid mechanics and applied mathematics are most welcome to join our group.
