Overview

I am a geomorphologist using a combination of remote sensing, environmental sensor networks, and numerical modeling to investigate earth surface dynamics and hazards, predominantly in mountainous regions. I am the 2020 EGU Outstanding Early Career Scientist in Geomorphology. 

My passion for geomorphology really started during a BSc and MSc in Geography at Durham University, where I studied glacial landsystems and paraglacial dynamics in Iceland with Dave Evans. In 2009 I moved to Switzerland to do my PhD with Peter Molnar at ETH Zurich. My PhD research focused on landslide and debris flow processes in a Swiss alpine catchment and culminated in a new model, SedCas, now being applied in other catchments to model sediment cascades and debris flow hazard. Following my PhD, I moved to the USA where I worked with Josh Roering at the University of Oregon on longer term landscape evolution in northern California and particularly the role of slow moving landslides. In a second postdoc at the US Forest Service and Colorado State University (2015 – 2016), I investigated the response of catchments in the Colorado Front Range to an extreme flood event and learned a lot about fluvial geomorphology whilst roaming around the Rockies with Sandra Ryan and Sara Rathburn.

I returned to the UK in 2017 as Lecturer in Physical Geography of Natural Hazards at UEA where I took advantage of the rich, interdisciplinary nature of the School of Environmental Sciences and started to build a research group. Since late 2019, I am a Lecturer in Physical Geography at the University of Exeter. I am PI on two recently funded projects, BOULDER, investigating boulder hazard cascades in Nepal and SCaRP, investigating cascading landslide hazards in the Philippines. I am Co I on Project GLOP investigating glacial lake outburst hazard in Peru. You can read more about these projects and my geomorphology group at my external website.

Research interests

My Geomorphology group at the Universities of Exeter and East Anglia studies earth-surface dynamics, hazards and sediment cascades predominantly in mountain landscapes. We use a range of techniques to quantify and monitor earth surface processes operating in these landscapes including remote sensing to detect landslides and passive and active sensors to track bedload transport in rivers. We are also actively developing spatially lumped, probabilistic models for simulating mountain basin sediment cascades and hazards. We are particularly interested in the response of landscapes to disturbances, whether that be a single extreme flood, an earthquake or longer-term climate change. We aim to both further understanding of earth surface processes and hazards and produce impactful research to enhance resilience to natural hazards. To that end, much of our research is based in developing countries, where populations are particularly vulnerable to natural hazards (e.g. SCaRP and BOULDER projects).
