Research Description

Population genetic structure and phylogeography of marine fishes; mechanisms affecting population distribution and gene flow in marine fishes. I use genetic methods, tagging studies, and physiological investigations to understand the influence of different processes on population structure and distribution, which allows prediction of how management policy, pollution, climate change, and interactions with exotic species may impact future distributions. This research also makes a significant contribution to the knowledge base required for implementation of ecosystem-based resource management.
