3D Modeling of Archaeological Collections: A Case Study in Archaeometry (2015)
Artifact collections and skeletal remains curated in multiple facilities and stored in variable conditions across the globe contain a wealth of archaeological knowledge. Access to data about these collections, much less the collections themselves, can be restricted both by policy concerns and practical considerations. Recent technological advancements have made creating high quality digital representations of both artifact and skeletal material possible. In this paper we compare two methods of...
3D Modeling the Sites of the Virgin Branch Ancestral Puebloan with Photogrammetry and BIM (2017)
On the Shivwits Plateau, there is scarce information concerning how the Virgin Branch Ancestral Puebloan people constructed their pueblos. This is a result of post-depositional processes that have destroyed much of the building materials. To overcome this hurdle, 3D Building Information Modeling (BIM) is allowing archaeologists to reconstruct these ancient structures digitally. These digital 3D models output volumetric data that are used to estimate material quantities, labor investments, and to...

Characterizing Hunter-Gatherer Ground Stone Bedrock Features in the Northeastern Chihuahuan Desert (2017)
Ground stone bedrock features are common at archaeological sites in the Lower Pecos Canyonlands of southwest Texas. These features are human-made depressions pecked, ground, or worn into bedrock or large boulders, and were used for a variety of processing activities by the indigenous peoples. Although archaeologists in the region have informally recognized different "types" of ground stone bedrock features (e.g., slicks, grinding facets, deep mortars), there have been no dedicated studies of...
Digital Archaeology and the Curation Crisis: 3D Modeling as an Answer to the Problems of Collections Access and Use (2014)
The archaeological curation crisis has plagued repositories and archaeologists alike with a multitude of problems for several decades, most notably inaccessibility to collections. Archaeological artifacts continue to be curated in repositories with little prospect of ever being used by researchers to uncover new information about the past, rendering them essentially useless and removing much of the moral justification of archaeology itself. However, in creating digital 3D models of artifacts and...

Movement in Moquegua: Detecting Differential Activity Types via the Knee in a Tiwanaku Subgroup (2018)
Previous studies regarding femoral fossa morphology center on risk levels and variables associated with non-contact anterior cruciate ligament (ACL) injury. Increased risk of ACL injury is associated with smaller femoral fossa size. While fossa size is influenced by many variables, biologically "plastic" responses to early life experiences, such as traversing local topography or cultural factors, are appearing to emerge as perhaps the most impactful. Due to the crucial nature of the knee, it is...
