	*Christopher Hein* is an associate professor and Director of Undergraduate Programs at VIMS. He received a B.S. from the Cornell University in 2003 and Ph.D. from Boston University in 2012. Chris works on aspects of coastal change ranging from the impacts of sea-level rise and past climate changes, to beach and dune management. He applies the tools of sedimentology and organic chemistry to investigate the link between sediment-supply driven coastal evolution and past climatic variability in coastal settings including barrier islands, marshes, beach- and foredune ridge systems, and coastal dunes, with a goal of using this link to forecast future responses to regionally-specific climate changes.
	Michelle Harris (Postdoc; BS, Sam Houston State Univ., 2016; MS (2019) and Ph.D (2024), U. South Carolina) is a Postdoctoral Research Associate for the Coastal Geology Lab at VIMS. She has earned her degrees in Geography with an emphasis on coastal processes, management, and remote sensing/GIS. She was a 2020 John A. Knauss Marine Policy Fellow where she was stationed within the NOAA National Ocean Service as a member of the Integrated Ocean Observing System (IOOS) Program Office. Michelle's doctoral research focused on managed mesoscale coastal dune systems in South Carolina using an integrated approach of field-based, remote sensing, and qualitative research. During her time as a member of the Wind-sediment Interactions and Nearshore Dynamics (WINDlab) at USC, she focused on quantifying the geomorphic response of coastal dune systems to natural (tropical cyclones, high tide flooding) and anthropogenic (e.g., sand fences) impacts. She is most interested in optimizing coastal management at varying spatiotemporal scales and communicating results with local stakeholders.
	Mary Bryan Barksdale (PhD Candidate; BA, Bowdoin College; MAT, University of Mississippi) holds a bachelor’s degree in Earth and Oceanographic Science and Gender and Women’s Studies as well as a Master of Arts in Teaching. Mary Bryan’s interest in the formation & evolution of coastal systems is rooted in her fascination with change occurring at the microscopic and molecular level. After thru-hiking the Pacific Crest Trail and teaching high school science for three years in a critical-needs school in her home state of Mississippi, Mary Bryan is focusing her love of environmental chemistry on the effect of salt marsh erosion on sediment and carbon accumulation rates within and across ecosystems. She is co-advised by Matt Kirwan.
	Kayla Cahoon (PhD Candidate; BS, W&M, 2019; VIMS PhD Student) is mapping the surficial geology of and studying Pleistocene sea-level change along Virginia's Eastern Shore. A W&M graduate in Geology, she completed an honors thesis studying impacts of land-use change on lacustrine sedimentation in the developed Lake Matoka watershed. Kayla started at VIMS as a MSc student, but her love of mapping the Eastern Shore has led her to recently transition to the PhD program.

Delaware, 2020; VIMS PhD Student) earned a bachelor's degree in Environmental Geoscience and master's degree in Geological Sciences. Liz's master's research was focused on improving mapping and stratigraphic analysis of the surface sands along the eastern shore of the Delmarva Peninsula. She is now working with collaborators from the U.S. Army Engineer Research and Development Center and Virginia Commonwealth University to quantify the tradeoffs between natural and artificial sand dunes along the North Carolina Outer Banks. Liz is also interested in leveraging coastal research to help guide local government in making more informed policy decisions regarding coastal management.
