Welcome to my homepage. This webpage is intended to give you a quick overview of my work and general interests. I am an Associate Professor and a Royal Society Research Fellow at Durham University. My research focusses on the dynamics of fluid flow and sediment transport over the surface of the Earth. I want to understand how simple flows can produce such a wide variety of landscapes. I study the flows themselve, but also the landscapes that they form. Additionally, I am interested on how these landscapes evolve over geological time-scales, and how part of these landscapes are preserved into the rock record. Where possible, I go out to measure flows in the field. If the flows are difficult to measure in the field, like the flows that occure on the bottom of the ocean, then I use computer models or physcial experiments to reproduce the flows in my computer or laboratory.
Currently, my research is mainly focused on flows that occure on the ocean floor. If one was to drain the oceans, then a landscape would emerge that hosts the highest peaks, the longest mountain ranges and the largest plains on our planet. Surprisingly the ocean floor is also covered by a network of channels that strongly resemble river channels. Hundreds of kilometre long stretches of meandering channels can be traced back to canyon that are wider and deeper than any we know on land. But how do these ocean-floor rivers work? How often are these rivers active? How do these rivers contribute to sedimentary and geochemical cycles that underpin the working of our planet? In my research I use the latest technologies to answer these questions.
