Hello! I am a Geoscientist specialising in using cutting edge, high-resolution, approaches to measure and understand the interactions of turbulent flow and sediment transport on our planet’s surface. I am currently a coastal observationist working on the BlueCOAST project:

I used a mix of MATLAB, python, ArcGIS and Global-Mapper to process geo-spatial and image data and plot for presentations and publications. I use a mix of Adobe Illustrator and InkScape to produce professional-standard figures suitable for publications and presentations. I have used C++ and MATLAB to run numerical simulations using the open source Computational Fluid Mechanics (CFD) engine OpenFOAM. I have years of experience in handling large datasets, from high-speed photography during my Masters and PhD thesis (using Particle Imagine Velocimetry and Infer-Red cameras), to DEMs produced via high resolution sonar (Multi-Beam-Echo-sounders), and laboratory laser scanners.
