Steve is a Professor in the Marine Science Department at Otago. He is a marine ecologist with a research emphasis on understanding food web structure and metapopulation dynamics within coastal marine communities. Together these processes are directly relevant to conservation and management of marine resources.
Steve’s research focuses on biogeochemical cycling in food webs to resolve how diversity of basal organic matter sources and changes to food web structure influence productivity and resource use by groups such as rock lobsters, reef fish, marine mammals and sea birds. The work involves direct observations, in situ experiments and state-of-the-art forensic chemistry, including stable isotopes and trace metal signatures.
Outside of Fiordland he has active research projects in Antarctica and the sub-Antarctic islands.
