Dr. David Gillett
Dr. David Gillett is an ecologist who specializes in studying the influence of anthropogenic disturbances and habitat quality on the community structure and ecosystem functioning of marine, estuarine and freshwater benthic communities. His research focuses on the development of biologically-based methods of habitat quality assessment in marine and freshwater systems using both traditional and molecular-based (e.g., DNA barcoding) tools. Specifically, he focuses on the development of causal assessment methodologies for California’s freshwater and marine habitats that use changes in biological communities to identify potential stressors to these ecosystems. He is leading efforts to develop of a causal assessment/stressor ID framework for California’s freshwater and coastal habitats in order to better understand and characterize the sources of impacts to biotic resources in these systems. He is also leading efforts to develop condition assessment indices for coastal habitats in California and across the country. As part of this, he is involved with expanding the use of genetic barcoding, metagenomics and eDNA as methods for the assessment of a variety of coastal habitats from the seagrasses of estuaries to the soft sediments of the continental slope.
He received a B.S. in marine science from Eckerd College in 1997, M.S. in marine biology from the University of Charleston in 2003, and Ph.D. in marine science from The College of William and Mary in 2010. He joined SCCWRP in 2010.
