My most recent research has focused on the use of handheld instrumentation for use in archaeology. This project has involved analysis of ancient pottery samples and obsidian projectile points. Using hand-held X-Ray Fluorescence (XRF) we have been able to discover an elemental pattern for pottery that originated from San Pedro de Atacama in Chile. This allows us to now analyze pottery found in household or burial sites in San Pedro or other locations for consistency with this pattern that can help us understand pottery trade distribution and changes in pottery production over time in this area. Similarly, elemental analysis of projectile points has enabled us to understand the number of different obsidian sources used in this area and help to discover their origin. This work has involved both on campus and off-campus (Chile) research with students.
