I have 35 years of experience and specialize in the field of coastal geology with specific knowledge in the areas of beach erosion, coastal wetlands and coastal sand dunes. I have published on such topics as the evolution of Boston Harbor, sand dune processes in the Gulf of St. Lawrence and Nantucket Harbor shore erosion. I have testified 12 times on topics such as beach accidents, construction on sand dunes and coastal flooding. I have extensive experience in shore erosion, beach processes, shore structures (seawalls, groins, jetties, revetments, breakwaters), beach accidents, sediment transport, coastal flooding, sand dunes, coastal wetlands, salt marsh processes, coastal construction, nearshore processes, dredging, beach accidents, coastal flooding, sand bars, estuaries and harbors.
