Personal profile

Research interests

My research focuses on the origins and evolution of ocean island volcanoes. My aim is to understand how island volcanoes grow and decay, at different time and spatial scales, and how that evolution reflects the holistic interaction between surface processes and deep earth mechanisms. My work also considers the hazard potential associated with island volcanoes, particularly how their gravitational collapse may trigger tsunamis that are theoretically capable of trans-oceanic devastation. I aim to establish the scale of risk associated with these events, drawing knowledge from one of the largest megatsunamis known from the geological record.

My work straddles the interface between volcanic field geology, geomorphology, stratigraphy, and sedimentology. I essentially combine detailed field observations with isotopic geochronology – such as Ar/Ar, U-Th, and cosmogenic 3He – to reconstruct the 4D evolution of ocean island volcanoes and their landscapes, followed by modelling to investigate the link between that evolution and its driving forces.
