CRHR, About Us

Who We Are

The Center for Regional Heritage Research (CRHR) is a community of scholars and researchers from across East Texas who investigate and document the natural and cultural heritage of the region.

This site serves as a digital repository for CRHR archaeological endeavors and others that occur within our service area, allowing access to our primary source material and supporting documentation in an accessible and streamlined format. We also allow users to post comments - should you feel so inclined - about each of our content entries. This function was initially included to foster and extend current dialogues regarding potential typological and functional attributes associated with the 3D scans and the catalog of Caddo NAGPRA vessels, but it extends to our other collections as well.

Our Team Members

Chief Designer
Robert Z. Selden Jr., Research Associate

Dr. Selden comes to the CRHR from Texas A&M University, where his dissertation focussed upon repurposing data collected through the practice of cultural resources management (CRM) for use in exploring macro-level trends across the larger regional landscape. His current research interests include the American Southwest, Caddo, ceramics, instrumental neutron activation analysis (INAA), ceramic petrofacies, ceramic petrography, radiocarbon, lithics, 3D geometric morphometrics, the Native American Graves Protection and Repatriation Act (NAGPRA), and evolutionary theory.


Timothy K. Perttula, Research Affiliate

Timothy K. Perttula (Ph.D. in Anthropology, 1989, University of Washington) is an archaeologist who has focussed for the 30+ years on the archaeology and history of the Caddo Indian peoples that lived in East Texas and the surrounding states. His particular research interests include the evolution of Caddo agricultural economies/subsistence systems; the development of political and religious organizations and rituals; the manufacture, decoration, and use of ceramic vessels; trade and exchange between Caddo peoples and between the Caddo and non-Caddo peoples; and the short- and long-term effects of European contact on the Caddo.


Bo Nelson, Research Affiliate

Mr. Nelson is an active archaeologist, and a partner at Archeological and Environmental Consultants, LLC, and is also the owner of Tejas Archaology. He has discovered and documented hundreds of archaeological sites, has authored or co-authored over 100 publications, and is one of the leading experts in identifying and locating archaeological sites in East Texas.


Leslie Bush, Research Affiliate

Dr. Bush operates Macrobotanical Analysis, a consulting practice focused on the identification and interpretation of plant parts found on archaeological sites. She has more than 20 years of experience analyzing archaeological flora from sites across a large portion of the eastern United States, from Texas to Iowa, Maryland and Florida. Her research interests include the history of plant cultivation and domestication, the recognition of ancient cuisines (as opposed to mere foodstuffs), the past distribution of plant species, and the reconstruction of ancient vegetation communities.
