My research interests are focused on applying process-based sedimentology to a range of applications including:
1. Better understanding how onshore sediment transport systems link to those in the deep sea, including the controls played by ocean currents on pollutant dispersal (e.g. microplastics)
2. Characterising seafloor geohazards, such as submarine landslides and turbidity currents, and determining how they are preconditioned, triggered and evolve downslope
3. Quantifying the rate and flux of deep sea sediment transport over timescales from minutes to millions of years, including the role played by climatic variations
4. Assessing risks posed to globally important seafloor infrastructure, such as telecommunications cables and pipelines, by submarine geohazards
5. Linking modern seafloor processes with ancient geological archives through integration of direct monitoring, repeat seafloor surveys, and sedimentary analysis
I work with a combination of data from outcrop and sediment cores, high resolution marine geophysical data, evidence of disruption and damage to infrastructure (e.g. cable breaks), and novel application of marine sensors to monitor sediment transport and geohazards, from sites spanning lakes, to fjords and the deep sea.
