Research Interests:   
Ideational cognitive archaeology, ancient art and iconographic systems, Native American myth, ritual, and cosmovision, applied anthropology. 

I am a cognitive archaeologist and artist and have spent more than 35 years studying one of the most significant bodies of hunter-gatherer mural art in the world – the Pecos River style (PRS) murals of southwest Texas and northern Mexico. These polychrome paintings were created nearly 6,000 years ago and remained in production for over 4,000 years. Using an interdisciplinary approach that integrates archaeological science, technical art history, materials analysis, and Indigenous knowledge systems, I have demonstrated that these murals are highly structured visual narratives rooted in enduring cosmological traditions. My work contributes to broader questions concerning hunter-gatherer complexity, the origins and persistence of myth, and the transmission of knowledge across generations as encoded in rock art iconographic systems.

I am currently focused on ongoing research and major writing projects, which necessitates a pause on new speaking engagements. I do not plan to accept new graduate students for Fall 2028.

Ongoing Research:
My ongoing research program includes Origins and Tenacity of Myth in Archaic Period Rock Art of Southwest Texas and Northern Mexico, funded in part by the National Endowment for the Humanities, and Layers of Meaning: Chronological Modeling & Pictograph Stratigraphy, funded in part by the National Science Foundation. These interrelated initiatives are subsumed under The Hearthstone Project, a collaborative effort between Texas State University and the Shumla Archaeological Research and Education Center. This long-term research program synthesizes expertise from archaeological science, formal art analysis, and Indigenous consultants to: (1) unravel the technical history of PRS murals and decode the symbols contained therein; and (2) build a chronological model of PRS pictographs. Results from this ongoing work are informing studies of myth, forager social organization, art history, and the origins of Mesoamerican myth and art, as well as research into possible drivers for the emergence and decline of PRS, including environmental, social, and extra-regional cultural influences. See the Blog Posts below for more information about the project. 

I am also engaged in a collaborative exchange bringing Indigenous knowledge-keepers and scholars into direct engagement with the region’s rock art—creating space to experience, interpret, and share living understandings of this sacred tradition. Across my work, I am committed to integrating rigorous scientific research with respectful partnership to advance both scholarship and heritage preservation.
