Biography

I am currently the Experimental Officer in the Sorby Environmental Fluid Dynamics Laboratory hosted within the Earth Surface Science Institute at the School of Earth & Environment. My research focuses on process sedimentology and I am interested in the fluid and sediment dynamics of natural systems. I undertook a Geology BSc at Bristol, an MSc in Sedimentology at Reading and a PhD at Leeds on the bend dynamics of submarine channel systems.

Research Interests

  • Experimental modelling of submarine channel systems.
  • The processes of sand injection.
  • Development of novel imaging techniques to monitor fluidised sediment systems.
  • Interaction of vegetation and coherent flow structures within rivers.
  • Development of new techniques in experimental sedimentology.
  • Application of PIV and LDA within experimental sedimentology

Current PhD Student and Projects

  • Jess Ross. Project Title: The dynamics of sand injectites and associated soft sediment deformation structures .
  • Kat Hunter. Project title: Mechanisms of auto-regulation in submarine channel-levee development.
