I am a geomorphologist with expertise in landslide mechanics, hillslope hydrology and development of environmental models. I am seeking to improve our understanding of the timing, size and location of landslides on natural slopes. I specialise in: 1) development of new models to examine the drivers and impacts of landslides, 2) development and application of remote sensing tools to collect landslide data; and 3) application of these models and datasets to address real problems for those exposed to landslide hazards worldwide. I also have an ongoing interest in hillslope and catchment hydrology not only for its impact on landslides but also for its role in controlling fluxes of water (and thus floods) and solutes (and thus pollutant concentrations) across landscapes. I am currently a Research Fellow in the Geotechnics and Structures Group in the School of Engineering.

Research Interests

Landslides are responsible for thousands of fatalities and millions of pounds of damage annually and are the dominant agent for erosion in steep landscapes worldwide. The geomorphic effect and destructive potential of landslides is driven by their timing, size and location. As a mathematically minded geomorphologist with expertise in landslide mechanics I am seeking to improve our understanding of the timing, size and location of landslides on natural slopes. I specialise in development of simple mathematical models to examine the drivers and impacts of landslides, in the development and application of remote sensing tools to collect landslide data; and in the application of these models and dataset to address real problems for those exposed to landslide hazards worldwide. I also have an ongoing interest in catchment hydrology and in particular in the impact of natural flood management on streamflow. Some areas of current or recent research include:

Analytical slope stability models

Landslides and landscape evolution

Landslide size and shape

Interactions between climate, vegetation and geomorphic processes (especially landslides)

Landslide detection from optical and SAR satellite imagery

Simple rules for landslide hazard

Co-seismic loess landslides

Landslide forecasting from rainfall characteristics and ground surface displacement

I am always looking for enthusiastic and curious potential PhD students with an academic background in earth or environmental science, hydrology, geotechnical engineering, geography, mathematics or physics.
