Bio

Sean is a postdoctoral researcher in the Coasts and Ocean Observing Laboratory at CSI.  He grew up in the marshes and swamps of Virginia and continues to focus on coastal wetland ecology.  Sean has a double major in English Literature and Environmental Science from The College of William and Mary, a master’s in Marine Biology from the Virginia Institute of Marine Science, and a Ph.D. from Florida International University. Sean’s research has focused on plant-soil interactions in coastal ecosystems, restoration, and disturbance ecology.

Sean lives in the Outer Banks, where he enjoys spending time on the water (surfing and kayaking), gardening, and playing soccer.

Education

PhD., Biology, Florida International University, Miami FL, August 2013- August 2018

M.S., Marine Science, Virginia Institute of Marine Science, The College of William and Mary, Gloucester Point, VA, 2013

B.A., Double Major in Environmental Science and Policy and English, The College of William and Mary, Williamsburg VA, 2007

Research Interests

Dr. Charles studies the ecology of coastal ecosystems and in particular the impact of climate change, cyclones, and anthropogenic impacts on ecosystem structure and function.  His primary interest is in maximizing the ecosystem services provided by coastal wetlands.

Current Projects

Quantifying the drivers of elevation change and sources of sediment deposition in Currituck Sound, NC

Identifying mangrove damage and recovery from tropical cyclones across the Caribbean

Mapping change in mangrove extent and carbon storage across the state of Florida
