David Samuel Johnson

Associate Professor of Marine Sciences, Virginia Institute of Marine Science
David Samuel Johnson, Ph.D., is a marine ecologist who studies how global changes (sea-level rise, climate change, ocean warming, nutrient enrichment, climate migrants) affect coastal ecosystems. He is interested in how ecosystems will be altered as viewed through the lens of animal and plant responses to these global changes. For instance, how does the spread of climate migrants, species the expand or shift their distributions due to climate change, affect the ecosystems they move into? He uses field observations coupled with field and laboratory experiments to answer these questions. He is an expert in marine invertebrates, especially worms, crustaceans, and bivalves.
