Biography

I am the Dean of College of Natural Sciences and a Professor in the School of Ocean Sciences, Bangor University. I completed my BSc (in Petroleum Geology) and PhD (on the sedimentology of modern beach and estuarine sediments of Carmarthen Bay, SW Wales) at Imperial College, University of London. I was then a postdoctoral fellow at the Wellcome Marine Laboratory, University of Leeds (1970-3), a research assistant in the Department of Oceanography, University of Southampton (1973-4), and a Royal Society Research Fellow at University College Galway, Ireland and Université de Perpignan, France (1974-6). I took up my post here in 1977.

Research Interests

My research interests encompass the sedimentary processes of continental margins from estuaries to continental slopes. My work has focussed on measuring lateral and vertical fluxes of sedimentary material (e.g. rate of infilling of estuarine sediments, settling flux of suspended matter on the shelf, cross-margin flux of suspended matter) and their relation to physical forcing (e.g. turbulence, resuspension, advection). These processes require an interdisciplinary approach and I am especially interested in biota-sediment interactions and their control of benthic-pelagic coupling: influence of micro- and macro-fauna on seabed properties and erosion rate, mediation of particle aggregation and settling flux by plankton. I also have an interest in sedimentary processes in the tropical lagoons of Mauritius. All of these studies have required the design and/or application of novel acoustic and optical technologies for remotely sensing sediment properties.
