Biography

In 1991, I graduated from Cornell University and Ithaca College (USA) with a BS in Engineering Physics and a BA in Physics. Then in 1992 I came to the School of Ocean Sciences, Bangor University to do an MSc in Physical Oceanography (awarded in 1994). After my MSc I spent a year at the Rosenstiel School of Marine and Atmospheric Science at the University of Miami, before returning to Bangor to register for a PhD. In 2001, I was awarded my PhD 'Modelling oscillatory flow over vortex ripples using the discrete vortex method' and have been a post-doctoral research assistant at Bangor since then.

Research Interests

The process of sand transport by waves and currents in coastal seas is crucially dependant on the interface between the sand at the bottom and the water above it. My work involves the use of computer models to mimic sand and water movement above this interface. Different strategies are used depending on whether the bed is rippled (corresponding to moderate flow conditions where the sand grains hop intermittently along the bottom) or flat (corresponding to more intense flow conditions where whole interface moves en-masse as a sheet). This work is important in understanding the process of sand transport because it determines how sand gets into the flow and which direction it will go. The long term goal of this work is to improve the sediment transport prediction in larger scale models which can be applied to practical situations such as the erosion of beaches and the changing morphology of coastal regions.
