Dr Matthew Lewis

I am a Research Fellow at Bangor University in physical oceanography. My research focuses on waves and tides, including applications to renewable energy and their role in coastal flood risk. My research uses computer models to numerically simulate wave and tide processes, including how these physical processes interact and how they may change in the future under climate change scenarios. 

My marine renewable energy research aims to characterise the resource (e.g. suitable locations) and oceanographic conditions (e.g. to inform resilient design of devices), as well as likely environmental impacts (e.g. stepping stones for the spread of invasive species or modification of the physical environment). My future flood risk research investigates how to downscale climate model information to impact (e.g. extreme weather conditions and flood extent).

I am interested in how physical process interactions may change in the future; such as river and storm surge flooding hazard in estuaries, or ocean-atmosphere exchange processes (e.g. wave-tide interaction). I also have interests in combining computer models of biological and physical processes to better understand the marine system. I am actively working in a number of research areas; future flood risk, estuarine processes modelling (flooding risk, morphodynamics), bio-engineering of marine renewables, tidal energy, wave-tide interaction modelling, baroclinlic modeling and larvae modelling. 

I am a STEM ambassador and have collaborated with historians (legends to validate climate models), local artists and wild swimming enthusiasts (predicting the movement of water), as well as: UK Met Office, CSIRO Australia, NIWA New Zealand, multiple universities in England and Wales.

I teach the ocean modelling module at Bangor Unviersity (OSX3016/OSX4012) and lecture for a number of modules.

I am happy to be an external PhD examiner, and have been on the subject of wave-tide interaction.

I have been an PhD examiner on wave-tide interaction modeling. 

I supervise many undergraduate and masters level research projects.

I currently supervise 2 PhD students and one KESS MRES:

Mike Case – impact of underwater noise propagation on fish.
Bernd Stephan – optimizing multiple tidal lagoon power plants.
