in situ sub-tidal surveys and experimental work which has spanned > 1500 research dives over the past 14 years. Much of my work has centered on investigating the effects of human stressors on marine ecosystems such as fishing, climate change and the introduction of invasive species. Central to my interests is the identification of alternative ecosystem states and processes influencing phase shift to less desirable states, particularly those that prove difficult to reverse.
