Teaching interests
I primarily teach on the MSc Coastal Engineering and BEng/MEng Civil and Coastal Engineering programs and am module leader for:
COUE508 - Advanced Coastal Engineering Modelling

Research interests
My research interests are generally focused on Offshore Renewable Energy. I have worked on studies into various wave energy devices, including the Anaconda and SQ devices - both deformable devices. I have also led studies into floating tidal energy devices and am currently leading Plymouth's contribution to various floating offshore wind research projects. I am also interested in the modelling of extreme wave interaction with floating devices and the design of moorings and electrical cables within arrays of offshore renewable energy devices.
Away from Offshore Renewable Energy I have carried out research into the interaction of two ships in close proximity and scour around monopiles. I am generally interested in all branches of physical modelling of wave, current and wind interaction with fixed and floating structures.
