### Research

#### Multiple scattering theory

- Analytical and numerical methods in multiple scattering theory (slab-clustering method, multipole technique, order-of-scattering, Foldy's approximation).
- Scattering by random arrays of cylindrical obstructions, directional spectrum of scattered wave fields, plane wave representation of cylindrical harmonics (integral representations of Bessel functions).
- Development of efficient methods for the scattering of water waves by a rigid or elastic structure (eigenfunction matching, integral equations).

#### Polar marine modelling

- Application of multiple scattering theory to ocean wave scattering by large fields of ice floes.
- Attenuation of ocean wave propagation through the marginal ice zone and evolution of the directional spectrum.
- Rheological models for wave attenuation in ice-covered seas.

#### Acoustics

- Application to design of sonic crystal barriers

#### Marine renewable energy

- Performance of large arrays of wave energy converters and their effect on wave climate near shore
