Ryan Institute Core Staff

The Ryan Institute is led by a Director, Deputy Directors and the Ryan Institute Executive Committee, supported by the Ryan Institute Operations Team and the Ryan Institute Technical Support Team. 



Deputy Directors

I am a marine ecologist with a particular interest in spatial ecology. I use experiments, survey, computer simulation and data analysis to understand patterns of population abundance and assemblage composition. My experience includes both benthic and pelagic ecology. The different approaches can be applied to address questions in conservation, fisheries, introduced species, monitoring, environmental management and compliance to legislation.
