Paul V. Heinrich graduated from Louisiana State University in 1976 with a BS in Geology. He earned his MS in Geology at the University of Illinois, Champaign-Urbana, in 1982, studying the sedimentology and stratigraphy of Pleistocene slackwater deposits in Southeast Illinois. At LGS he has been involved in a number of projects involving the Quaternary and archaeological geology in Louisiana and in the Southeast United States. Research interests include geologic mapping at 1:24,000 and 1:100,000 scales; geomorphology and subsurface stratigraphy of the Willis and Citronelle formations; meteorite impact craters; neotectonics within Southwest Louisiana; stratigraphy and geomorphology of Pleistocene sediments composing the Louisiana coastal plain; and geoarchaeology of the coastal plain of Louisiana and adjacent states. He has worked for the Illinois State Geological Survey, conducting field studies for the Rural Abandoned Mine Program; as an exploration geologist for Placid Oil Company in Denver; as a Field Archaeologist for Prewitt and Associates Archaeological Consultants, Inc., Austin, Texas; and as a consultant conducting studies of and co-authoring reports on either the archaeological or environmental geology of project areas for various companies, including: Coastal Environments Inc.; Earth Search, Inc.; Gilbert/Commonwealth Associates, Inc.; R. Christopher Goodwin and Associates, Inc.; Iroquois Research Institute; Reid Company, Inc.; and Prewitt and Associates Archaeological Consultants, Inc.
