Mr. Hartwell is the Program Manager for DRI's Community Environmental Monitoring Program (CEMP), a program that directly involves members of the public in the operation of a network of radiation and weather monitoring stations located in communities surrounding and downwind of the Nevada Test Site. He is presently serving as Deputy Director of the Division of Earth and Ecosystem Sciences. Mr. Hartwell's archaeological research has focused on three geographic regions: the southern Great Basin, the southern Great Plains, and the pampas of Argentina. Specific interests include hunter-gatherer lithic technology, caching behavior, quarrying behavior, and soil formation processes. Specific research has included recent investigations of a historic toll road in north-central Nevada, an examination of quarrying behavior in the southern Great Basin, late Paleoindian lithic technology on the Plains, and participation in a study comparing and contrasting human adaptation on the U.S. southern Great Plains and Argentinean pampas. In addition, Mr. Hartwell has recently studied how popular culture can affect the public perception of science, most recently speaking as an invited participant at a workshop on "Comet and Asteroid Impacts and Human Society". He also has produced a publication for the general public that discusses archaeological research at Yucca Mountain on the Nevada Test Site.
