Research Emphasis

I use an interdisciplinary approach to detect marine habitats and to evaluate anthropogenic factors on food webs and communities. I conduct research in both estuarine and marine ecosystems. Specifically, I focus on 1) anthropogenic effects such as those related to climate change and invasive species, on the biology and ecology of invertebrate populations and their associated communities, 2) linkages of foundation species that span ecosystems and their effects on habitats and species interactions 3) detection and characterization of benthic communities using remote sensing techniques.
