I am a coastal geomorphologist with a broad interest in Quaternary environmental change. My research focuses on understanding the geomorphic evolution of clastic coastal depositional environments such as estuaries and incised-valleys, coastal plains, and dunefields in response to fluctuations in relative sea-level, changing climatic conditions, and the impact of tectonics. This involves reconstructing how coastal environments changed during the late Quaternary, using coring techniques to unlock sediment archives, and geophysical techniques such as chirp sonar and ground-penetrating radar to ‘image’ the sub-surface. This data is bought together in a GIS to produce 2D and 3D maps and models of the evolution of coastal environments.
Relative sea-level change is the most significant driver of the evolution of coastal environments during the Quaternary. A major thread of my research is reconstructing how relative sea-level has changed around the New Zealand coast over the past 10,000 years (the ‘Holocene’). This involves recovering and analysing indicators of past sea-level, and using these indicators to reconstruct how relative sea-level has changed over both space and time. This research seeks to understand complex processes such as glacioisostacy and hydroisostacy that drives considerable spatial and temporal variations in Holocene relative sea-level change around the New Zealand coast, and provides invaluable context to our understanding of how New Zealand’s coastal environments have evolved during the late Quaternary.
My research has two main areas of focus:
