I am a geomorphologist interested in hillslope and fluvial processes, currently based at the University of Potsdam, Germany. My research focuses on identifying and understanding controls on the structure and organisation of fluvial networks from hilltops down to floodplains. I work with high resolution DEMs derived from lidar data.

Research

Geomorphic feature extraction from lidar

In order to understand controls on fluvial systems, it is essential to quantify and extract signatures of geomorphic features from the landscape. To do this I develop new techniques for analysing high-resolution topographic data to extract features such as river channels, floodplains, and terraces.

As part of this research I am involved in the development of LSDTopoTools, which is open source software for geomorphological research. Our software aims to facilitate the production of reproducible topographic analysis. For example, we have developed algorithms to extract accurate channel networks, perform chi analysis on river profiles, extract hilltops using flow routing, and analyse bedrock outcrops using topographic roughness. See our LSDTopoTools website for more details.

Structure and organisation of fluvial networks

Another key part of my research is investigating how climate and tectonics control the structure and organisation of flvuial networks, such as the drainage density, channel steepness, and planform geometry of networks. I use high-resolution topographic data to explore the links between climate, tectonics, and fluvial network structure from a range of landscapes.
