I am Reader in Fine Particle Dynamics in the School of Ocean Sciences, and specialise in the erosion, transport, and deposition of fine, cohesive sediment. I graduated from the University of Utrecht (the Netherlands) with a combined BSc/MSc in Sedimentary Geology in 1988. At the same university, I completed my PhD in Bedform Dynamics in 1993. Subsequently, I was Postdoctoral Research Fellow at Geomar Research Centre in Kiel, Germany (studying Late-Pleistocene climate signals in slope sediments from the North-Atlantic continental margin), at the University of Rouen, France (on resuspension processes in the Seine estuary and gravel mining in the English Channel), and at the University of Bergen, Norway (investigating grain orientations in turbidite deposits).
In 1998, I moved to the School of Earth and Environment at the University of Leeds, where I started as a Marie Curie Research Fellow and then became a Senior Research Fellow. My research in Leeds included the physical properties of particulate density currents and their deposits and the dynamics of turbulence-modulated flows carrying cohesive clay particles. I took up my present post in Bangor in January 2007.
I am a process sedimentologist with more than 25 years of experience in sediment transport in fluvial, shallow marine, and deep-marine environments. My main fundamental and applied research interests include physical and biological cohesion in fine-grained sediment, the dynamics of sedimentary bedforms, and sediment gravity flows in the deep ocean, but my expertise also stretches to hydraulic engineering, palaeoclimatology, and mathematical modelling. I combine experimental research with field work to answer timely research questions, taking a blue-skies approach as well as collaborating with industry.
