    Research interests

    I am an anthropological archaeologist with a specialty in North American hunter-gatherer-fishers of the west. Interests include evolutionary ecology, ethnoarchaeology, archaeometry, residue studies, psychoactive plant use, colonial encounters, collaborative research and contemporary indigenous communities. I have a broad background in academic, tribal, and cultural resource management archaeology. Although most of my recent research is based in the Pacific Northwest and California, I have been involved in field research throughout the eastern and southwestern United States, and the Dordogne Valley, France. I am developing a research program in the Columbia Plateau region and am accepting graduate students whose interests overlap my own.

    Current Research

    I am broadly interested in the relationship between forager decision making and environmental variability across time and space, and understanding how different adaptive strategies may alter these dynamics over the long term historical record. Guided by models from evolutionary ecology, this work involves examining some of the ideas and assumptions of interpretive frameworks that evaluate the productivity and potential of certain resources or environmental zones.

    Plateau Archaeology
    The Plateau region of North America is an exceedingly interesting yet relatively understudied region. Because of our geographic position, our history of research, and our commitment to collaboration with local tribes, there are abundant research opportunities at WSU for students interested pursuing Plateau based studies. I am currently developing a regional research program and am actively seeking talented students whose research interests overlap my own. There are numerous possibilities involving museum collections and collaborative studies, and I encourage students to contact me if they are interested in developing a particular idea or research project.

    Historical Ecology of the Pacific Northwest
    Most of my current research is directed at understanding human-environment interactions in the southern Pacific Northwest Coast-throughout the Holocene into the present day. My dissertation research, developed in collaboration with the Tolowa of northwestern California, involved excavations at a series of sites in the Smith River basin, oral history documentation, and archival research. A major focus was to understand some of the profound changes that occur in subsistence and human organization after people begin living in large semi-subterranean plank houses at about A.D. 700, developments that are probably reflective of a region-wide adaptive shift in social systems and residential patterns that cross-cut linguistic boundaries and ecological zones.

    Similar changes are being documented in more recent work focused on Native American use of marine resources, which includes documentation of coastal and estuarine sites and Traditional Cultural Properties, test excavation and fine grained analysis of subsistence remains, and ethnoarchaeological work with descendant communities. Initial results indicate a fundamental restructuring in use of these environments, with a distinct shift to logistical strategies, storage, and intensive shellfish procurement, marine mammal hunting and fishing of mass harvested species (smelt, salmon) after A.D. 725. Studies with Tolowa and Yurok people who continue to traditionally harvest seasonally spawning smelt has been enormously helpful in modeling extractive methods, storage and discard patterns in the past.

    I am also keenly interested in how human-environment dynamics changed in post-contact times, through the American colonial period into the present day. Studies are developed to incorporate issues of concern to descendant communities that are grappling with how to respond to threatened access to critical marine foods and the natural and human induced impacts on these resources. The research program is relevant to these issues in that it seeks to establish historic baselines and to better understand long term human-environment interactions while integrating cultural knowledge and oral history documentation within the process of recording sites and Traditional Cultural Places.

    Residue Studies: Human Use of Tobacco and other Psychoactive Plants in the Ancient Americas
    Other research focuses on the application of archaeometric techniques to anthropological questions about the history of human use of psychoactive plants. Contact period peoples throughout the Americas widely used plants with stimulant or hallucinogenic properties (e.g., tobacco, coffee, cacao, cassina, datura) for medicinal, ceremonial or recreational purposes, yet surprisingly little is known about their use in the past. Gas Chromatography-Mass Spectrometry (GC-MS) analysis offers a direct means to track ancient use of such plants by identifying alkaloid residues in ancient artifacts. With Jelmer Eerkens (UC Davis Anthropology), Mine Palazoglu and Oliver Fiehn (Fiehn Metabolomic Laboratory, UC Davis) I have worked on method development and refinement of residue extraction and analysis techniques. For example, our studies include work on smoke plants (in ancient pipes) and medicinal teas (in shell and pottery vessels) through identification of plant biomarkers, experimentation ("smoking" plants in experimental pipes, brewing medicinal beverages), and residue extraction from ancient specimens. A major focus is to develop the most powerful and least destructive methods possible that will have a wide range of future applications. Archaeological applications include studies directed at understanding the cultivation, range extension, and management of tobacco in western North America. For example, nicotine, a biomarker for tobacco (Nicotiana sp.), has been identified in ancient pipes from the southern Pacific Northwest Coast dating to as early as the 9th millennium AD., an area where the antiquity of tobacco smoking was, until now, unknown. In addition to tobacco, method development includes the chemical characterization of a suite of key smoke plants used by ethnographic hunter-gatherers (e.g. kinnikinnick or Arctostaphylos uva ursi, widely used by Pacific Northwest peoples) so that we may potentially identify prehistoric use of these plants. Other work includes identification of caffeine residues on shell and pottery vessels associated with Ilex vomitoria, a plant used to brew cassina, or the black drink, a caffeinated ceremonial tea famous for its use in purification rituals by elite males in the southeastern United States.

    Graduate and undergraduate student projects and internships

    Research opportunities for graduate students include masters and dissertation level projects based on original fieldwork and/or museum collections from northwestern North America, especially the Plateau and Northwest Coast areas. See link to list of projects below.

    Undergraduate opportunities include directed research projects and (for credit or volunteer) internships. Interns enrolled in ANTH 498 or ANTH 499 earn academic credits and contribute to scientific research while gaining valuable experience working with archaeological materials. They must commit to working in the laboratory for a set time and number of hours every week. In the spring of 2014 students will assist with at least two projects including one where they will sort and identify marine foods found in samples from sites in the southern Pacific Northwest Coast and another helping to document a wide range of stone tools and perishable materials from Rock Creek Shelter in southern Oregon. SPRING 2014 INTERNSHIPS ARE NOW FULL. Please contact me in you are interested in internship opportunities for Fall 2014 or later.

    There are also abundant opportunities to help with the digitization and presentation of museum materials. Again, I encourage students to contact me about these opportunities.
