William Chadwick is an archaeological geophysicist, geoarchaeologist, and director of Archaeological Services who conducts research on landscape and environmental change related to historic and prehistoric archaeological sites.

William ChadwickChadwick holds a PhD in Geology from the University of Delaware, where he gained extensive training in archeological geology, ground-penetrating radar (GPR), quaternary geology, sedimentology, stratigraphy, and geomorphology. His dissertation, titled "Paleogeographic and Paleoenvironmental Reconstruction of Terrain Associated with Coastal Prehistoric Archaeological Sites, Cape Henlopen, Delaware," utilized geophysics and intertidal coring to reconstruct the terrains and environments related to the construction of prehistoric shell middens on relict recurved spits in Cape Henlopen State Park, Delaware.

Chadwick is a registered professional archeologist (National, #12322) and licensed professional geologist (Utah, # 5556501-2250) who has broad experience in both geoarcheology and archeology.

Chadwick comes to IUP with extensive experience in applied archaeology, having worked within cultural resource management consultation for over 17 years. He has conducted numerous geoarcheological examinations of paleogeographies and paleoenvironments and geophysical surveys related to both historic and prehistoric archeological sites and their environs throughout the Middle-Atlantic, Mid-Western, and New England regions. Experiences in geomorphic assessments include surveys within glaciated, coastal, and fluvial systems. Notable geomorphic assessments in fluvial settings include deep testing on floodplains of the Schuylkill River and Susquehanna River in Pennsylvania, the Potomac River in Virginia and Maryland, and the Wabash River in Indiana, in addition to smaller rivers and streams. Other areas of expertise include geospatial predictive modeling, quantitative and statistical analysis, and the utilization of GPS and GIS in archaeological research.

His experience in archeology includes all phases of excavation related to prehistoric and historic period sites throughout the Mid-Atlantic and New England regions. Chadwick's research interests include archaeological geophysics, intertidal archaeology, and the application of geospatial technology to archaeology.

Chadwick teaches courses in World Archaeology, Cultural Resource Management, Archaeological Geophysics, and Geospatial Technologies
