Landslide and Tsunami risk
I'm working with NOCS, Manchester, Aberdee, Dundee, Ulster and BGS on how warming in the Arctic might increase the risk of a landslide-generated tsunami to the UK coastline. I will be working on both the landslide and tsunami propagation modelling using Fluidity.
Combining simulation and field data will give new insight into past environments. I'm using a suite of models including GOTM and Fluidity to investigate the effects of stratification, tides and mixing on oceanic conditions and how these might get preserved in the geological record.
My main research interests are Oligotrophic plankton blooms, nutrient transport, and turbulence models.
I'm working on a project with Queens Belfast on how emplacement of marine renewable energy devices might affect the surrounding environment in terms of ecology and wider-area effects. This work is being done mainly with Fluidity and MIKE21, but also with GOTM and a range of other models.
My main area of interest in HPC is in novel technologies, such as Cell and GPGPU. I am also interested in adaptivity and parallel scaling.
I am one of two authors of a geological process modelling code, GPM. This code originated in Schlumberger. The main author of the code is Dan Tetzlaff. GPM simulates both siliciclastic and carbonate sedimentation over geologic timescales. I wrote the carbonate sedimentation portion of the code and have authored a number of papers based on the insights gleaned from this model.
I'm currently working on embedding a sediment model within Fluidity. Our aim is to simulate turbidity currents at a wide range of scales, making use of the adaptive mesh framework. Coupled with the existing tidal model and a forthcoming spectral wave model, the addition of sediment model will make Fluidity a very capable coastal ocean model, capable of simulating a wide range of environments.
