Research interests

My research addresses fundamental questions about the response of coral reefs, reef landforms and mangroves to environmental change, and the geomorphologic processes that control the evolution of Quaternary tropical coastal and shallow marine sedimentary environments. Much of my early research was focused on quantifying the process controls on Holocene carbonate sediment and reef framework production and preservation. This work was subsequently extended to encompass the development of high-resolution framework and sedimentary indictors of reef depositional environments and events. Much of my recent research has focused on applied aspects of contemporary reef geomorphology that seek to address issues associated with the effects of natural and anthropogenic disturbance, and environmental and climatic change on the functioning, stability and sustainability of tropical coastal and shallow marine sedimentary environments.

Research projects

Key current research areas:

(1) Impacts of environmental change on reef growth and shallow marine carbonate accumulation

Research in this area focuses on quantifying the effects of anthropogenic and environmental disturbance on reef carbonate production and on coral reef growth. Major on-going projects are: (i) examining Holocene reef development under naturally ‘marginal’ marine environmental conditions (especially those of high turbidity and high terrigenous sediment input); and (ii) developing novel census-based methods to assess rates of reef carbonate production and coral reef accretion.

(2) Geomorphology and resilience of coral reef islands

Research in this area is focused on developing an improved understanding of the underlying controls on the initiation and subsequent development of low-lying coral reef islands, and on using an improved understanding of reef island geomorphology to better understand island resilience and their potential responses to future environmental changes. Much of this current work is being conducted under the auspices of the IAG working group REEForm.

(3) Marine carbonate sediment production in fish

Research in this area has evolved from novel work undertaken in 2009 that provided the first descriptions of the sedimentary products of carbonate precipitation in tropical marine fish. Presently, this work is being extended to examine the preservation potential of these carbonates in different tropical marine environments, and to examine the products and preservation potential of marine fish carbonate production in temperate water settings.
