Research Interests

I am an ecologist that research environmental impacts on coastal plant and animal communities. My research focuses on how human stressors, such as bio-invasions, pollution, and climate change, impact the structure, productivity and biodiversity of aquatic ecosystems. I combine experiments, surveys, analysis of long-term dataset, modeling and meta-analysis, to test how patterns in biological communities are generated and maintained. My research provides predictions on how coastal habitats will respond to human stressors and recommendations for conservation strategies needed to ameliorate their impacts.
