My interests are varied and diverse. I study material science as it relates to archaeological resources and how we can answer specific questions, using experimental archaeology, that relate to site formation processes, residue analysis in ceramics, ceramic analysis and artifact usage. Through this process I have learned to exactly replicate Anasazi, Paiute, Thule, Paquime and Mimbres vessels. In the study of ceramic residue analysis, we have partnered with faculty in the Chemistry department, HRC and the Physics Department and we have learned much about how residues are preserved in ceramic vessels and modified through time. This can inform us on how vessels were used and what they were used for. Using FTIR and XPS surface analysis we developed non-destructive analysis techniques for ceramic vessels and sherds that are reliable and robust.

I am interested in constructing and deconstructing cultural process theories taking a post-modern approach that does not confound or bloviate concepts and paradigms. My focus is currently on applying Chaos theory to archaeological models and issues such as equifinality and culture change through time.

Most recently I have been examining the genetics of maize and how current information can inform us as to how maize horticulture and specific strains of maize diffused throughout the Southwest. I will be presenting a paper on this research at the NAA meetings in Minden Nevada on April 12, 2008.
