My Research
I am primarily interested in modelling two- and multi-phase flows in natural environments and particularly with volcanological applications. Currently, the primary focus of my research concerns the settling of volcanic ash in the atmosphere, and in particular the influence of instabilities at the base of the ash cloud. Through a combination of theoretical and numerical modelling, analogue experiments and field work, we investigate the effect of ash concentration and size, as well as wind drag and buoyant spreading on the settling dynamics.听This work has implications for the interpretation of ash deposits, and the assessment of hazard associated with ash dispersal.
My wider research includes magma mixing and mingling, sediment transport problems including the aeolian remobilisation of volcanic ash as well as bedform development in rivers and deserts, and modelling ballistic trajectories of volcanic ejecta, as well as more general fluid dynamic phenomena.听
