Current Position (28/01/2008 onwards):

Marsden Post-Doctoral Fellow, Massey University, New Zealand

Joining the Marsden Research Project: Capturing the secrets of a life-sized lahar (MAUX0512)

Focus: Analysing field measurements from the 18 March 2007 Ruapehu lahar, N.Z. and rain-triggered lahars at Semeru, Indonesia. Investigating bulking and debulking of these lahars. Developing a theoretical function to describe the time-dependent entrainment and deposition processes of lahars, for use in numerical models.

PhD (2003-2007), Bristol University, UK:

Analogue and numerical modelling of gravity currents and pyroclastic flows

Focus: Developing a 2-layer numerical pyroclastic flow model using the Finite Volume Method in C++, modelling granular column collapse, box models of fluidised granular flow and laboratory experiments investigating fluid gravity current flow.

Thesis advisors: Prof. Steve Sparks & Dr. Heidy Mader

Funding: NERC (19/09/2003-19/09/2006)
