Research

Research Interests

Stress and disturbance ecology, Trophic connectivity

Current Research Areas

The aim of this research is to determine the processes that supply seaweed wrack from reefs. This research is looking at the role of storms on this export and the relative importance of two major pathways of transfer of organic matter, dislodgment of whole thalli and erosion of kelp tissue.
