Hein WM Photo Christopher Hein is an associate professor in the VIMS Department of Physical Sciences. 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. He also serves as the co-director for the VIMS - William & Mary Undergraduate Program in Marine Science.
