Chris Keylock returned to full-time academia when he joined the department as a Prize Senior Lecturer in July, 2010. He works at the interface of engineering, physics and earth sciences on a range of phenomena. Current research interests include:
- The dynamics of mass movements (avalanches) and granular shear flows;
- Turbulent flows over complex surfaces and the elucidation of flow structures;
- Wavelet methods for nonlinear and chaotic phenomena;
- Risk analyses for mass movements.
